为研究新巨龙煤矿6305工作面过地堑构造区域时断层滑移失稳特征，基于数值模拟，分析了采动影响下地堑构造区域断层面应力特征及演化规律，并根据断层滑移倾向性指标TS分析了地堑构造区域断层的滑移过程。研究结果表明，在6305工作面推进过程中，断层面稳定性受剪切应力影响更为敏感，剪切应力的变化对断层滑移倾向性TS的变化起主导作用；地堑构造区域FL37、FL39断层发生阶段性滑移，FL37断层靠近覆岩区域最先发生滑移，随后滑移区域从高位岩层逐渐向低位岩层演化，而FL39断层则与之相反，靠近煤层区域最先发生滑移，滑移区域出由低位岩层向高位岩层演化；在工作面过地堑构造区域过程中，工作面向地堑构造区域开采断层滑移诱发冲击的危险性大于工作面位于地堑构造区域。研究结果对类似条件下的工作面安全开采具有一定的借鉴意义。

 In order to study the characteristics of fault slip instability when the 6305 working face of Xinjulong Coal Mine passes through the graben structure area, based on the numerical simulation, the stress characteristics and evolution law of the fault surface in the graben structure area under the influence of mining are analyzed, and the slip process of the fault in the graben structure area is analyzed according to the fault slip tendency index TS. The results show that the stability of fault plane is more sensitive to shear stress during the advancing process of 6305 working face, and the change of shear stress plays a leading role in the change of fault slip tendency TS. In the graben tectonic area, FL37 and FL39 faults slip stage by stage. FL37 fault slips first near the overburden area, and then the slip area gradually evolves from the high rock layer to the low rock layer. In contrast, FL39 fault slips first near the coal seam area, and the slip area evolves from the low rock layer to the high rock layer. In the process of working face crossing the graben structure area, the risk of mining fault slip induced impact in the graben structure area is greater than that in the graben structure area. The research results have certain reference significance for the safe mining of working face under similar conditions.
