Background technology
Gas is initial stage of the archaeophyte in accumulation coal-forming, and the action breaks of cellulose and organic matter through anaerobic bacteria form.
High temperature, high pressure environment in, while coal-forming, due to physics and chemical action, continue to generate gas.Gas be it is colourless,
Tasteless, odorless gas, but the fragrance of similar apple can be smelt sometimes, this is due to that aromatic hydrocarbon gas are same with gas
When the reason gushed out.Gas is 0.554 to the relative density of air, and the density of gas is 0.716kg in normal conditions, gas
Penetrating power be 1.6 times of air, be insoluble in water, it is not combustion-supporting to maintain to breathe, when reaching finite concentration, can make one because
Anoxic and suffocate, and can occur burn or explode.Gas is with existing for free state and sorption state in coal body or country rock.
Coal industry is one of China's pillar industry, but the death toll of coal production is the world that other countries of mining are dead
Die total number of persons four times, wherein accident account for significant proportion caused by gas explosion.The gas detector that the country uses at present
Power consumption is big, short life, sensitivity is not high, accident notice not in time, cause accident to find in time.And it can not supervise in real time
Data are surveyed, flase drop, missing inspection easily occurs, very big hidden danger be present.Even if detecting place where the accident occurred, it can not be accurately positioned and accuse
Know rescue personnel, delay the rescue time of preciousness.
