深部复杂构造区域冲击地压控制技术研究

Study on Controlling Technology of Rock Burst in Deep Complex Structure Area

赵各庄煤矿3137工作面上部9层煤开采边界不整齐,造成顶板不规则冒落,并在部分区域形成局部高应力集中现象。针对此情况,以赵各庄煤矿3137工作面为原始模型,采用FLAC、RFPA数值模拟软件对深部复杂构造区域诱发冲击地压的机理和过程进行研究和分析,为以后的巷道布置和支护设计提供理论依据。

The 3137 working face of Zhaogezhuang Coal Mine is of large mining depth and synclinal structure distribution.The irregular mining boundary of the upper 9 layers of the working face causes irregular roof caving,which may form local high stress concentration in some areas and form high abutment pressure in the working face 3137.Taking the 3137 working face of Zhaogezhuang coal mine as the original model,this paper studies and analyzes the mechanism and process of rock burst induced by deep complex structure area by using FLAC and RFPA numerical simulation software,which provides theoretical basis for future roadway layout and support design.
