摘要：
According to HuaFeng Coal Mine, it is explored that the solutions of coal pillar bearing large, leaving hard, and prone of rock burst in thick seam with high outburst-proneness in deep mine based on microseismic monitoring. Taking No. 1411 face for instance, the study identified the technical proposal of vertical completed pillarless entryway driving along goaf. High roadway deformation and frequent rock burst of the mine roadway caused by the roadway driving along next goaf with a narrow coal pillar between No. 1410 blew drift and No. 1411 up drift were treated and controlled. The research results show that: the convergence between roof and floor was reduced by 132mm. The mine earthquake levels, released energy and frequency decreased significantly. Above M=0.9 were reduced 86%, 94% reduction in the release of energy.
