常兴煤矿边角煤开采技术研究

Study on boundary coal mining technology of Changxing Mine

针对常兴煤矿2108工作面留存边角煤较多、支护难度大的问题,结合其煤炭资源的赋存条件,设计了2108工作面边角煤连续开采方案。实践证明,该方案能够保证2108工作面边角煤安全可靠回采,有效减少了工作面搬家次数,提升了开采的连续性。通过加强支护的方式,保证了2108工作面边角煤开采的安全性。

Based on the difficult support and boundary coal in 2108 working face of Changxing Mine,combined with conditions for the coal resources occurrence,continuous mining scheme of 2108 working face boundary coal was designed.The practice showed that the plan enabled to ensure the safe mining of the working face,reduce the working face removing,improve the continuous mining.The strengthened support ensured the safe mining of boundary coal in 2108 working face.
