Green mining method for recovering triangular coal pillars
The invention discloses an environment-friendly mining method for recovering triangular coal pillars, which comprises the following steps of: 1, recovering a triangular coal pillar area formed at the end stage of mining of a coal face by utilizing a strip type mining filling method; according to the method, the triangular coal pillar area is filled with the pasty fluid filling material through the designed pasty fluid filling material, so that land loss caused by surface collapse after the triangular coal pillar is mined and recovered is avoided, and green recovery and mining of the triangular coal pillar are realized.
本发明公开了一种回收三角煤柱的绿色开采方法，包括回收三角煤柱的绿色开采方法，步骤如下：步骤一：对采煤工作面回采末期形成的的三角煤柱区利用条带式回采充填法进行回收。本发明通过设计的膏体填充料，对三角煤柱区通过膏体填充料进行填充，避免三角煤柱开采回收后导致地表塌陷而使其土地流失，实现对三角煤柱绿色回收开采。
