摘要:
在近距离煤层群的开采中，工作面巷道位置选择直接影响其支护方式、顶底板管理等生产工作。为了得到下位煤层工作面切眼的合理位置，利用基于三维显式有限差分法的计算工具Flac3D，以矿井近距离煤层9、101、102为工程实例，分析了在近距离煤层群回采时期，下邻近层综采工作面切眼位置与上邻近层预留保护煤柱错距。结果表明，上邻近层回采后，在其因支承压力和拉张作用下的下沉盆地中岩层内，主要发生塑性变形；上覆岩层破坏范围为26m，底板破坏范围为5.6m，采空区左右两侧破坏范围3~5m；下位煤层10603工作面切眼与上位煤层9煤保护煤柱错距应大于5m。
Abstract:
The position of working face roadway directly influences its support way, roof and floor management, and other production work in mining of close distance coal seam group. In order to get the reasonable position of open-off cut in working face of the lower coal seam, the computing tools - Flac3D based on three dimensional explicit finite difference method was applied. Taking the close distance coal seams 9th, 101th, 102th as engineering examples, the alternate distance of open-off cut in the fully mechanized working face of lower adjacent coal seam to guard coal pillar in upper adjacent coal seam during the stoping period of close distance coal seam group was analyzed. The results showed that after the stoping of upper adjacent coal seam, the plastic deformation is mainly distributed in rock strata of subsidence basin under the effect of abutment pressure and tensile. The damage range of overlying strata is 26 m, the damage range of floor is 5.6m, and that in both sides of goaf is 3-5 m. The alternate distance of open-off cut in the 10603 working face of lower coal seam to guard coal pillar in 9th of upper coal seam should be greater than 5m.
