[0002] Coal mine gas, also known as coal seam gas or coal-bed methane, is a mixed gas composed of methane, carbon dioxide and nitrogen that escapes from coal and surrounding rocks. Gas is a harmful factor in coal mine production. It not only pollutes the air, but also when the gas content in the air is 5% to 16%, it can cause explosions when encountering fire, causing accidents. Gas refers to the harmful gas mainly composed of coal-bed methane in mines, sometimes methane alone. Gas is a colorless, tasteless, odorless gas that can burn or explode. It has higher diffusivity than air. Gas is non-toxic, but when the concentration is very high, it can cause suffocation. It needs to be extracted before coal mining to prevent dangerous accidents.
