摘要
根据实践总结在地质构造复杂的煤层中,工作面上下巷长度不等距;为提高资源回收率,工作面临近收尾时,通过旋转采煤工艺的实施,多回收了煤柱,减少了资源浪费,大大提高了资源回收率,收到了显著的效益。
According to the practice of complex geological structures are summarized in the coal seam.The upper and lower face length is not equidistant Lane. To improve resource recovery,workfaee almost ending, through the implementation of rotation mining techniques.Multi-pillar recovery of the reduced to waste of resources and greatly improving the resource recovery, received a significant benefit.
