摘要
基于8311工作面回采期间运输顺槽侧顶板出现冒落现象,通过分析顶板冒落的原因,提出冒落区施工人工假顶、煤壁注浆以及顺槽施工恒阻组合锚索等联合维护措施,控制了顶板冒落、下沉现象,保证了工作面安全高效回采。
Based on the roof caving phenomenon in the side of transport channel during the mining period of 8311 working face,by analyzing the causes of roof caving,this paper puts forward some joint maintenance measures such as artificial roof,coal wall grouting and constant resistance combined anchor cable in the caving area construction,which can control roof caving and subsidence,and ensure the safe and efficient mining of working face.
