| Abstract: | The sources of gas emission at a coal face were divided into three parts: the coal wall, the mined coal and the goaf, and the formulas of calculating the quantity of gas emission in each part were given. The pattern of gas emission was studied for mining process, different mining sequence for group of coal seams and slice mining for thick coal seams. And the new achievements of control principle and technique were discussed for gas emission by using different ventilation systems, pulsing ventilation and gas drainage at coal face in China. Finally, the control practice of gas emission at sub level coal face with a gas emission quantity of 150 m 3/min was introduced. |
