摘要
针对深部孤岛综采工作面在末采期间,位于三角区且遇到断层,利用层位对比和断层揭露情况分析断层走势,合理确定停采线位置,优化了收尾过断层方案。首次实施由顶板注浆改为煤壁注浆施工工艺,确保过断层有效控制顶板。两巷采取掏槽木垛、加长超前支护、支架架脚点柱措施,为顺利收尾创造了条件。给出了抹角大小确定方法,不但保证了设备回撤空间,而且减少了工程量。
In view of the deep island comprehensive mining face in the late mining period ,it is located in the triangle area and encounters faults. For the first time, the top grouting technology was changed from top grouting to coal wall grouting technology to ensure the effective control of top grouting. The two lanes adopt the measures of cutting wood pallets,lengthening leading support and stent foot column,which create the conditions for a smooth end. The method of determining the indirect size is given, which not only guarantees the return space of the equipment,but also reduces the quantity of the project.
