摘要
煤矿综采工作面在生产中经常发生片帮冒顶事故,不仅使工作面产量降低,同时对人身安全造成严重威胁。通过对综采工作面片帮冒顶的机理及特点进行分析,提出综采工作面片帮冒顶的控制措施。
In fully mechanized coal mining face, the accidents of rib spalling and roof fall commonly occur in the production not only to reduce the output but also to threat seriously human security. The control measures of rib spalling and roof fall in full mechanized working face are proposed based on analyzing the mechanism and characteristics of rib spalling and roof fall in full mechanized working face.
