为有效防治冲击矿压灾害,利用FLAC3D数值模拟软件模拟了新兴矿开采上、下解放层对被解放层的卸压效果。结果表明:上解放层开采,63#煤的开采对65#煤起到一定的应力解放作用,但是不够充分;上解放层开采,65#煤的开采对于67#煤起到了解放作用,由于65#煤开采后的底板破坏深度最大为24 m,卸压深度最高达65 m左右,对67#煤的顶底板起到卸压作用;下解放层开采,67#煤的开采顶板破坏高度要大于底板破坏深度,其卸压高度约为70 m左右,对65#煤起到了很好的解放作用。 In order to effectively prevent and deal with the rock burst, FLAC3D numerical simulation software was used to simulate the relief effect of the upper and lower liberated strata on the liberated layer of Xinxing Mine. The results show that the exploitation of 63 # coal plays a role of stress relieving to 65 # coal in the upper liberated layer, but it is not sufficient enough. When mining on the liberated layer and mining of 65 # coal, it plays an emancipating role for 67 # coal. The depth of destroying floor after coal mining is up to 24 m, and the maximum pressure relief depth is about 65 m, which plays a role in pressure relief on the roof and floor of 67 # coal. Under the conditions of the liberated layer mining and 67 # coal mining roof damage height is greater than Depth of destruction of the floor, the pressure relief height of about 70 m, 65 # coal played a very good liberation.
