欢城煤矿二号井村庄下压煤开采设计分析

Design for Mining under Village in 2nd Mine of Huancheng Colliery

针对西辛庄村煤柱被欢城煤矿二号井与七五煤矿共同压覆,村庄搬迁社会问题极度复杂等现实情况,根据本采区开采技术条件提出村庄下压煤条带开采方案,并通过理论计算预计出各方案实施后的地表移动和变形值,在计算开采损害赔偿的基础上对各方案进行了效益分析,确定出最优方案。实践表明,此方案成功地解决了村庄下大量压煤和村庄下不搬迁开采问题,对煤矿建(构)筑物下压煤开采设计具有重要的指导作用。

The north and south of coal pillar under Xixinzhuang Village belonged to 2nd Mine and Qiwu Colliery,so the village move was a very difficult problem.Several strip mining projects were put forward based on mining technology condition of this area and surface movement and deformation value of these projects was obtained by calculation.On the basis of mining damage compensation calculation,benefit of every project was analyzed and optimized project was obtained.Practice showed that this project solve the problem of mining under village without moving the village which also provided important reference for mining under buildings.
