摘要
综采工作面过断层时若不采取合理的回采方法及安全措施,不仅降低了工作面回采效率,加大了煤柱损失,而且过断层期间很容易发生安全事故。对此,方山店坪煤矿在202工作面过F0断层时,决定尝试采用松动爆破法,实践证明取得了显著成效。
If the reasonable mining method and safety measures are not taken during the overfault of fully mechanized mining face, it not only reduces the mining effciency of working face and increases the loss of coal pillar, but also is easy to occur safety accidents during fault crossing. In this regard, Fangshan Dianping Coal Mine decided to try to adopt the loose blasting method when it crossed the F0 fault in No. 202 working face. The practice has proved that remarkable results have been achieved.
