综采工作面冒顶事故预防及处理预案

Research on Fully Mechanized Working Face Roof Caving Accident Prevention

结合煤层赋存条件复杂、顶底板稳定性差的情况,吕家坨矿业分公司通过分析煤层赋存条件、综采工作面冒顶情况,从技术、生产管理方面入手,完善了处理程序、管理要求等综采工作面预防冒顶方案,进一步提高应对回采过程中抗顶板事故风险和灾害的能力。

Combing complex coal seam conditions,poor stability of the roof and floor conditions in Lyujiatuo Mining Branch,by analyzing coal seam mining condition,fully mechanized coal face roof fall situation,from a technical,production management aspects,improved processes,regulatory requirements,etc.Mechanized mining face caving program further improved dealing with roof accident risks in the process of extraction and disasters and improved the stopping rate.
