跨采暗斜井工作面相关参数优化研究与实践

为了减少资源损失，需要在保护穿层暗斜井安全稳定的前提下，合理规划跨采工作面煤柱及终采线位置等相关参数。以山西神州煤业4102工作面为工程背景，通过理论分析上部煤层开采过程中的围岩应力分布情况和底板损伤状态，当穿层暗斜井位于上部正在回采工作面下方时，根据分析计算结果进行优化决策，确定了4102工作面跨采行人进风斜井延深段的布置方式。与原工作面布置方式相比，优化后该工作面可多回采出约2.2万t优质主焦煤，对于进入资源枯竭阶段的矿井具有可观的经济效益。

Optimization Research and Practice of Related Parameters of Working Face Which on the Top of Dark Inclined Roadway

When cross measure dark inclined roadway pass through the mining face that is being worked above, it is necessary to rationally locate coal pillars and the stopping line so as to reduce the resource loss under the premise of protecting the safety and stability of the cross measure inclined roadway. This paper theoretically analyzes the stress distribution of surrounding rock and damage state of the floor during the extraction of the upper coal seam against 4102 long-wall panel of Shanxi Shenzhou Coal Mine. Based on the calculation results, the optimization is proposed. Compared with the layout of original working surface, the extension arrangement of the inclined shaft is determined when the 4102 long-wall face is in above. This can recover about 22,000 more tons of high quality main coking coal, which has considerable economic benefits for mines entering the resource depletion phase.
