摘要
基于王坪煤矿8304工作面过β3煌斑岩期间造成的回采难度大、回采率低的情况,通过优化传统回采工艺,采用导硐法过β3煌斑岩,原煤产量增加1.74万t,成效显著。
Aiming at the mining difficulty and low recovery ratio in crossing β3 lamprophyre at 8304 fully-mechanized working face in Wangping Colliery, the paper presents the optimization of traditional stoping technology by pilot tunnel method, which has increased the coal production by 17400 tons.
