Abstract
Due to the comprehensive mechanized mining intensity great,production concentration,the speed of promotion quickly,a large area of goaf formed. A lot of gas gathered in the goaf and often cause gas tail-entries in working face and back to romantic (especially in the upper corner),this se-verely restrict the safety of mine production.In the paper summed up the control method of the upper corner gas which used present commonly,and real-ized drainaging goaf gas is an important way to prevent the gas of the upper corner accumulation.,and put forward using resistance curtain、auxiliary fan and drainage pipe together. The reference experience is provided for the prevention and cure of coal and gas outburst in mines.关键词
