In order to meet the needs of mine rescue operations, the KJT95 mine disaster relief communication system was successfully developed during the Ninth Five-Year Plan period. The key achievements and achievements are briefly described below.
2 Key Scientific Research Achievements 2.1 Research on Methane Detection Components Fushun Branch began to develop methane components, ie, thermal catalytic elements, in the early 1960s. It matured in the mid-1980s and was at the leading level in China at the time.
The use of methane detection elements in underground coal mines generally has the following problems: First, the service life varies, some components can reach i2 years, and some can only be used for half a year; the second activity declines too quickly, and the stability is poor. Sensitivity is calibrated in a week, and it takes a lot of work when used in transit; Thirdly, when the component is in a low concentration of methane (concentration 10% CH4), the component will be activated, and its sensitivity will increase. , And it is not easy to recover in a short time, so it will make the test result produce a positive error.
We conducted in-depth research on the above-mentioned problems in domestically produced components to improve and improve component characteristics, so that domestic components approach or achieve the technical level of foreign components.
2.2 WCP8501 gas pipeline combination sensor The WCP8501 gas pipeline combination sensor centrally detects gas concentration, temperature and pressure, and its structure is divided into upper circuit.
The central sensor package assembly, the lower sampler.
Sampler. The humidity inside the gas pipeline is very large, it is easy to collect water, and the dust is also very large and it is easy to attach and deposit on the gas pipeline protrusions. Therefore, the sampler must be able to prevent the sediment from clogging the sampler after a long period of operation.
The sampler is inserted into the gas pipe to face the direction of the air flow and an air inlet hole is opened. An air outlet hole is opened opposite to the air flow direction. A baffle plate is fixed in the middle of the sampler to create a pressure difference between the air inlet hole and the air outlet hole. The airflow in the sampler has a part of the airflow upwards and passes through the sensor package assembly. When the general gas drainage pipeline is designed, the drainage flow is designed within a certain range, so the internal resistance of the sampling reactor is also within a certain range. Considering the need of calibrating the sensor and cleaning the sampler, an external hole is provided on the sampler, when the external hole is required for calibration and cleaning, the standard gas or air is connected, and the negative pressure air intake drawn in the gas pipe is used to achieve The role of calibration and cleaning. The entire sampler is finally processed with precision to achieve anti-rust requirements.
Sensing device package assembly. All sensor components of the WCP8501 type gas pipeline combination sensor are housed in the central component. The sensor component encapsulates the lower component of the component, contacts the gas of the gas pipe, and the upper part leads to the circuit of the sensor by the electrical lead. The upper and lower parts are blocked by the sealing material and the gas extraction part is blocked by powder metallurgy. The whole structure has explosion-proof performance and prevents the gas gas inside the gas pipeline from leaking out.
The sensor's sensitive component selection. The gas concentration detection sensor is a LX-R1 type carrier thermal conductor produced by the Fushun Branch of the Coal Science Research Institute. Its performance: bridge voltage 3.5V, bridge current 170mA, minimum sensitivity (LX-R1 type carrier thermal conductivity element measurement linear range is very narrow, only 0 ~ 30% CH4 is linear, and in 30% ~ 100% (range The measurement curve of gas concentration in the gas is non-linear, and the sensitivity of the carrier heat-conducting element will decrease when the CH4 is over 30%, and the higher the gas concentration, the more the sensitivity will decrease.For this reason, we use the polyline nonlinear transformation circuit to perform linearity. According to the actual measurement curve, we can select two correction points to meet the measurement error requirements: The first calibration point is selected at the concentration of 33% CH4, and the second calibration point is selected at the concentration of 66% CFU. It ensures that the gas concentration measurement does not exceed the allowable range in the entire measurement range.
The temperature measurement sensor in the WCP8501 gas pipeline combination sensor uses the AD590 series integrated temperature sensor manufactured by Analog Devices.
The pressure sensitive components of the WCP8501 gas pipeline combination sensor use IC sensors' pressure sensitive components.
The WCP8501 type gas pipeline combination sensor is selected from the IC sensor company's TO-8 package structure type 13A absolute pressure sensor, with a temperature compensation function, and with a gain setting resistor.
The three sensor components of the WCP8501 type gas pipeline combination sensor are collectively packaged in a single component. The entire sensor is small in size, and only one sampling port is required in the gas pipeline to reduce the installation work on the site, and the maintenance is simple, avoiding the measurement of the gas pipeline in the past. Distributing sensors is not easy to manage and use.
2.3 High-precision micro-pressure sensor With the application of pressure equalizing ventilation and fire extinguishing technology and the pressure equalization technology in the goaf area in the safety production of coal mines, the resolution and accuracy of high-precision micro-pressure sensors play a key role. The development of the GY-1 high-precision micro-pressure sensor provides a new monitoring tool for the safety production of coal mines.
Relative Humidity: Piezoresistive sensors use integrated circuit manufacturing technology to generate diffusion resistors directly on semiconductor substrates and form bridges. Since semiconductor materials are silicon materials, piezoresistive sensors are often referred to as diffusion silicon pressure sensors.
Because the gas pressure in the coal mine is sometimes under the influence of factors such as blasting and switching dampers, sudden changes occur. Therefore, the sensitive components of the pressure sensor are required to resist pressure rushing for a certain period of time. 39 hit the ability. The pressure resistance of the general pressure sensitive element itself is 10 times of the full scale.
The selected pressure sensitive element has a full-scale range of 1 kPa, a maximum overload capacity of 3 kPaD, and a GY-1 high-precision micro-pressure sensor buffer device designed to withstand 10 times the full-scale pressure in 5 seconds. In order to ensure that the device can work in coal mines for a long time, a filter is installed at the air inlet to prevent the underground dust from entering and plugging the orifice.
Temperature compensation of the output signal of the pressure sensitive element: When the temperature of the pressure sensitive element increases, the following characteristics are exhibited: 1 Pressure sensitivity decreases; 2 Resistance of each piezoresistance increases. GY-1 high-precision micro-pressure sensor has been deeply studied in the selection of the entire sensor, electronic circuit design, and digital processing to ensure that the sensor can reach the predetermined technical indicators.
In the laboratory, zero-drift test evaluation of the sensor, constant pressure load test test, low temperature zero test assessment, high temperature zero test assessment and other four assessment. After industrial tests, the “National Key Scientific and Technical Research Project of the Ninth Five-Year Plan†was completed. GY-1 high-precision micro-pressure sensor fills the gap in the field of high-precision pressure measurement for mines in China and has reached the leading domestic level. The sensor has been proved by laboratory and industrial tests to be suitable for all kinds of pressures in coal mines. Monitoring place. The sensor's sensitive components have strong reliability, strong pressure impact resistance suitable for the harsh environment of coal mines, secondary amplifier circuit selection of high-precision instrumentation amplifier, signal processing using single-chip digital technology, the whole machine has the advantages of high measurement accuracy, high display resolution. The sensor has been inspected by the national coal mine explosion-proof and safety product quality supervision and inspection center.
2.4KJT95 mine rescue and disaster relief communication K.IT95 mine rescue and disaster relief communication system is an ideal communication method for mine rescue teams. This system is the national “Ninth Five-Year Plan†research project. This subject is for existing communication system problems. Combining the national scientific research achievements of the "Seventh Five-Year Plan" and "Eighth Five-Year Plan" for mine communication technology and drawing on domestic and foreign advanced technologies, it has been developed. The system has a simple structure, stable performance, convenient networking, and high reliability.
The system can improve the rapid response capability and cooperative combat capability of mine disaster rescue, and the mine rescue work can reach a new level. In the disaster relief command operation of the mine, in order to quickly understand the disaster situation, timely and correct formulation and implementation of disaster relief programs to reduce accident losses Personal injury and death provided protection.
The system includes KJT9501 communication host (referred to as the host), KJT9502 communication auxiliary machine (referred to as the auxiliary machine), KJT9503 communication mobile phone (mobile phone for short), KJT9504 communication line package (referred to as the line package), KJT9505 wrapped car (referred to as line car) and other equipment. The main unit is used by the underground command center; the auxiliary engine and mobile phone are used by the rescue personnel in the disaster area. The ambulance team uses the mobile phone (via the auxiliary machine) to speak to the host, and the team members can use the mobile phone to directly contact each other. The underground headquarters can directly access the Inoue headquarters through a ready-made telephone line, and the Inoue headquarters can intervene in the disaster relief communications command if necessary. The ambulancemen carried the ready-made wrappings with them. When the disaster relief operations proceeded, they were automatically put on the line while they were on the move, and they were in constant contact with the underground command headquarters and the Inoue headquarters. The communication cable serves as an adventure rope for the ambulance team.... The line car does not go down when it is in actual combat. Its role is to use it to re-wrap the reeled bag into a bag for re-use.
Some mine rescue teams in the provinces of Suzhou, Anhui, and Yunnan have been equipped and used, reflecting very good results.
The KJF2000 monitoring system has the functions of environmental monitoring, tape fire prediction, spontaneous fire prediction and production monitoring in the goaf area. Environmental monitoring - mainly monitoring the operating conditions of various toxic and harmful gases and working face in coal mines, such as methane, carbon monoxide, oxygen concentration, wind speed, air temperature, rock coal temperature, roof pressure, air pressure, smoke and dust concentration, etc.; Surveillance - monitoring of various production parameters of in-flight and downhole production processes and operating parameters of critical equipment such as coal bunker coal level, pump status and drainage test, hoist, fan, pressure fan, belt conveyor, coal mining Machines, switches, magnetic starters, power supplies and other operating conditions and parameters.

The simple block diagram of the entire system shows the downhole substations and sensors installed in underground coal dust, biogas, carbon monoxide and other hazardous gases environment, real-time monitoring and processing of various safety and production parameters under the coal mine, and safe production. The parameters are transmitted to the ground station in time. All kinds of data are processed by substations and central stations, and sound, light alarms, and power-off control signals can be directly sent as required. The ground center station uses a dedicated communication cable to communicate with the downhole substation via the KJFS modem (MODEM). The KJF2000 system can accurately and completely understand the downhole safety conditions and production conditions, realize early prediction and forecast of disaster accidents, and can automatically handle them in a timely manner.

The system can be flexibly configured according to the needs of users.
3 Industrialization of scientific and technological achievements Industrialization of scientific and technological achievements, transforming scientific research achievements into commodities and realizing their own value, the only purpose is to enable them to produce good social and economic benefits. The industrialization of scientific research results not only requires the industrialization of results, but also the commercialization of products. As the main transformation base of scientific research achievements, the goal is to enable those countries with new high-tech and high added value products and key promotion products of the industry, and the latest research achievements to be market-oriented to the maximum, and accelerate the marketization of scientific and technological achievements and industries. The speed of the transformation not only needs to meet the needs of the domestic market, but also strives to beat the international market to form a first-class scale of benefits.
Therefore, in the next few years, a large amount of funds will be invested, with planned, step-by-step, more in-depth market development and promotion of existing products, continuous expansion of market share of products, increase market share of products to ensure the scientific and technological advantages of enterprise products. Become economic and social benefits.
3.1 Industrialization of disaster gas sensors and sensors Since the late 1950s, the Fushun Branch took the lead in the development of carrier catalytic elements for methane detection. In the late 1970s, electrochemical carbon monoxide and electrochemical oxygen sensors were developed. They were developed in the late 1980s. Ethylene sensor, carbon dioxide sensor, developed a colloidal electrolyte carbon monoxide sensor in 1990s. The safety monitoring system started earlier in China's coal mines. In the 1970s, five companies produced gas detection and power cutoff instruments. In the 1980s, it began to equip coal mine environmental monitoring systems by introducing foreign advanced technologies. Since the end of the 1980s, it has absorbed foreign technology. Absorb and summarize the characteristics of coal mines in China to develop and develop an environmental safety monitoring and monitoring system. There are more than 20 kinds of detection and monitoring systems available, and they are widely used in various coal mines.
According to statistics, there are 649 key state-owned coal mines in China, including 129 pairs of gas outburst mines, 136 pairs of high-gas mines, accounting for more than half of the total number of mines, spontaneous combustion mines accounted for 61%, casualties and state assets caused by gas explosions and mine fire accidents. The loss has always ranked first in the world. Although China has successively used foreign technology to develop and develop sensors with various parameters. However, due to the low production level of domestic sensors, especially gas sensing devices, and the backwardness of production equipment, the product performance has never been substantially improved. The key reason for the current safety monitoring system is that the sensor has a short lifetime and poor stability, and the system cannot operate normally. Some mines have to purchase large quantities of similar foreign products for many years. Secondly, there is no uniform standard for existing monitoring systems, and they are incompatible with each other. There is no standard for field-level buses, which results in system interfacing equipment not being able to achieve open interoperability.
Fushun Branch of China Coal Research Institute is the first company to research, develop and produce coal mine safety professional research units for carrier catalytic elements, methane sensors, colloidal electrolyte carbon monoxide components, ethylene sensors, carbon dioxide sensors, ultrasonic vortex wind speed sensors, and micro pressure sensors. The scale of production of the above products has been expanding year by year. Therefore, it was adopted on the basis of the original research and development capabilities and technologies. 41. Equipment investment, expansion and the introduction of foreign advanced equipment production lines and other process manufacturing technologies will reach world advanced levels in the short term and meet the needs of mines, petrochemicals and other industries for disaster gas monitoring. It is undoubtedly an investment-funded innovation fund with few benefits and quick results. Significant shortcuts for economic and social benefits.
3.2 The industrialized gas management of coal mine gas detection device products is a problem that all major coal mining countries in the world are trying to solve. Gas prediction and monitoring are major gas disaster prevention and control methods and have achieved great development in recent years. The Fushun Branch of the General Branch of the Coal Science Research Institute is a professional research institute for coal mine safety. Its research, design and production in this field has been at the leading level in China. It has now formed a series of products including coal seam gas multiparameter detectors, portable methane detectors, and high and low grades. Concentration A sensor, methane power meter, wind power gas lock device, etc. 'Coal seam gas multi-parameter analyzer is the national scientific research achievement of "Seventh Five-Year Plan", "Eighth Five-Year Plan" and "Ninth Five-Year Plan" scientific and technological research projects. It is a leading level in China and has won national and ministerial awards. It is a practical experience and experiment of underground coal mines. The result of combining experimental results with computer technology. A variety of important parameters of coal seam gas can be quickly, accurately and directly measured in a simple and convenient way. Products have obtained explosion-proof certificate and coal mine safety instrument certification.
The portable methane analyzer is a portable methane detection instrument, which is characterized by small size, convenient portability, intuitive detection, and low cost. It is used by coal mine gas crews and management personnel to wear or hang on the work surface as a gas detection alarm. Wide range of products. This product has obtained explosion-proof certificate, coal mine safety instrument qualification certificate and measurement certificate in 1997.
Wind power gas lockout devices are frequently developed for gas disasters in China's coal mining work face. As early as in the 1980 edition of the "Coal Mine Safety Regulations," the "Wind Power Lockout Device" has been proposed, and the 1986 edition of the "Coal Mine Safety Regulations" proposed "three specialties." Locking "facilities. The current 1992 edition makes it clear that two lockouts (wind power locks and gas locks) should be installed on all excavation facets in gas venting areas, high gas mines, coal (rock) and gas (carbon dioxide) outburst wells. When the local ventilator stops running or the gas concentration in the excavation tunnel exceeds the limit, all the power in the local ventilator power supply roadway can be automatically cut off immediately. The local ventilators shall provide power for the three specialties (special transformers, special switches, and dedicated lines) (Article 134). This is the "three special and two locked" facilities. Therefore, simply speaking, a wind power gas lock device is a safety monitoring device that realizes two locks.
Fushun Branch successfully developed China's first wind power gas locking device in 1987, and won the third prize for scientific and technological progress of the Ministry of Coal in 1989. Continuously summing up the production practices for many years, as well as opinions and suggestions from various coal mines, and tracking the latest level of the latest electronic technology, several changes were made to form the current production ang in 1997.
It has the advantages of small size, simple and reliable system, etc. It is a necessary safety equipment for the coal mining face.
The methane power-off meter is a device that realizes methane detection display and over-limit alarm on the coal mining excavation face and mobile equipment, and performs breakpoint locking and unlocking control on the controlled electrical equipment. According to the number of control devices, it is divided into single-point, two-point, and three-point power-off meters. It has become an indispensable safety monitoring device in coal mine production.
Our gas detection equipment includes: coal gas methane multiparameter analyzer portable methane detector; wind power gas lock device; single, two and three methane power off device; onboard methane power off device; vehicle methane power off device; Special monitoring equipment (derived products designed according to user requirements). In the future, investment in monitoring equipment should be increased. The need for investment is mainly considered from the following points: This series of products B was identified by the coal industry as a conventional device for underground safety monitoring, and the Ministry of Coal had promoted the use of it in an administrative subsidy manner. Most of the products used by early investment do not meet the new industry standards and have already expired.
The space for the promotion of local coal mines in the country is extremely large. Because this series of products has low investment, is easy to use, easy to maintain, and can easily be expanded into a small set of safety monitoring systems, it is also very suitable for local coal mines.
Due to historical reasons, large and medium-sized state-owned coal mines have used products from the 1970s and 1980s for gas detection, and these products have disadvantages such as difficulty in maintenance and complex operations, and most of them have been replaced by new ones. This series of products fully considers the compatibility with the old system from the design, so it is an ideal replacement product.
3.3 Industrialization of the KJF2000 monitoring system As mentioned above, this system has a variety of monitoring functions. It has been used in coal mines since 2001 and has been welcomed by the scene. So far, more than 100 sets have been promoted and applied in the coal mine system.
The Fushun branch specialized in the establishment of personnel at the measurement and control center and software center, which has accelerated the industrialization process of the KJF2000 monitoring system and has now formed an industrialized operation mechanism.
In short, with the deepening of the transformation of scientific research institutes, Fushun Branch has made great efforts in the industrialization of achievements, which has opened up a broad prospect for the survival and development of branches.
