本煤层顺层钻孔瓦斯抽放及消突效果考察

Effectiveness of Drillhole Gas Drainage and Elimination Working Seam Bedding

为了消除采煤工作面煤与瓦斯突出危险,在鹤壁煤电股份有限公司十矿1307工作面采用了本煤层顺层钻孔进行抽放,并根据《防治煤与瓦斯突出规定》和《煤矿安全规程》采用残余瓦斯压力法、残存瓦斯含量法和统计煤层瓦斯预抽率对工作面瓦斯抽放进行消突效果考察,对工作面安全生产起到一定的指导意义。

In order to eliminate coal and gas outburst danger in the coal mining face,the bore holes were applied to the seam of No.10 coal mine 1307 coal mining face in Hebi Coal and Electricity Co.,Ltd.of the tenth mine for the gas drainage.According to Regulations on Coal and Gas Outburst Prevention and Control and The Coal Mine Safety Rules,the residual gas pressure method,residual gas content method and the gas drainage rate before the mining operation method were applied to the investigation of outburst elimination.It will play a guide on safety mining operation of the coal mining face.
