摘要
以1306工作面为研究对象,从矿山压力、支架工作状态、回采工艺和地质条件等多个方面阐述了破碎顶板端头冒漏机理,并以此为依据,提出了改善支架工作状态、优化拉架工序、合理控制采高等预防支架端头顶板冒漏的措施。
Taking 1306 working face as the research object, this paper expounded falling and leaking mechanism of broken roof end from the aspects of mine pressure, support working state, extraction process and geological conditions, and on this basis, proposed measures for improvement of support working state, optimization of opening process, reasonable control mining height to prevent roof falling and leaking of stent end.
