Gases and Gas Detection Methods in the Coal Mines

an explosion is possible. When miners know where gas is accumulating it is then possible to dilute the gas by the addition of fresh air, thus lowering the concentration of the gas. methane (firedamp) carbon monoxide (chokedamp) and carbon dioxide Canaries to Detect Gases in Coal Mines Miners once used canaries to test the air quality in the mines.

Risk Assessment of Miners’ Unsafe Behaviors: A Case Study

for Chinese coal mines, but also for many other countries, gas explosions are a serious threat [11–15]. For example, mining is a very important industry in Poland. One of the most common hazards in a coal mine accident is methane, so the fatality rate of gas explosion accidents is very high. When the situation

Coal Types, Formation and Methods of Mining

Conventional mining is the oldest method and accounts for only about 12% of underground coal output. In conventional mining, the coal seam is cut, drilled, blasted and then loaded into cars. Continuous mining is the most prevalent form of underground mining, accounting for 56% of total underground production.
