摘要
本文通过对城郊煤矿受断层影响的综采工作面进行优化设计,提出了台阶形和扇形回采三角煤的工作面布置方式,解决了工作面丢三角煤的问题,提高了工作面回采率,为今后类似条件下综采工作面的合理布置回采提供了一定的技术基础。
Based on the optimization design of fully mechanized coal face influenced by distributed fault in Chengjiao Colliery, the author has represented the layout of bench and fan face to extract coal in the triangular area, which has improved the recovery coefficient and provided a technological basis for similar fully mechanized coal face.
