摘要
基于S5-13工作面过邻近F5断层应力区时出现煤壁片帮严重、顶板破碎、支架倾架等现象,为了保证工作面安全高效回采,采取了顶板预裂泄压、支设U29型工字钢棚、注浆等联合维护措施,保证了工作面安全快速过断层应力区,取得了显著成效。
When the S5-13 working face passes through the stress area adjacent to the F5 fault,there are some problems such as rib spalling on the coal wall,broken roof and tilting support.In order to ensure safe and efficient mining in working face,joint maintenance measures such as roof pre-fracturing and pressure relief,support of U29 I-shaped steel shed and grouting were adopted,which ensured safe and rapid crossing of fault stress area in working face and achieved remarkable results.
