The difference between coal mine gas mask and old dust mask

The use of gas masks in coal mines has always been the key to coal mining. Through the comparison of a large number of dust-proof tools, we have found that in the original case, the coal dust that occurred during the excavation and coal mining was We only use simple protective masks. Such masks can only eliminate a small part of coal dust, but there is still a large amount of coal dust that remains in the human body. It is precisely this kind of coal dust that really threatens safe production and workers. Health, what is the difference between the simple dust masks and the current professional coal mine respirator?

The main difference is that the old dust masks are poor in breathability, and the so-called breathability is not good. Many workers who reflect these dust masks will feel an unusual feeling of sulking. Workers work underground, and the entire air flow is not particularly good. After doing a lot of physical labor, if there is a lot of heat inside the mask, it will inevitably cause the entire sulking phenomenon to become more serious and inconvenient to use. Workers cause great confusion and eventually cause safety accidents. In particular, the emergence of pneumoconiosis, and if it is the use of coal mine gas mask, there will be no feeling of sulking, natural protection for pneumoconiosis is also very perfect.
