摘要
针对黄白茨近距离煤层开采,下层煤1016工作面回采时由于受0916,0918工作面采空区集中应力和上层遗留煤柱影响,经常发生片帮冒顶等严重现象,采用滑移线场理论分析对下位煤层影响范围与现场实测等研究方法探讨片帮冒顶原因,通过以护为主、控制支架仰角、合理进刀、调整平衡千斤顶等综合预防措施和片帮冒顶针对性的处理手段,实现了安全回采,取得较好效果。
In order to solve the problem of coal-wall sliding and roof falling in mining 1016 Face influenced by concentration stress of 0916 and 0918 gobs, slip-line field theory was applied to analyzing mining influence range, cause of coal-wall sliding and roof falling was discussed on the basis of observation data. By comprehensive prevention measures including supporting, controlling support eleva- tion, rationally cutting, adjusting balance jack, safe mining was realized and good effect was made.
