摘要:
为降低工作面过断层时采动应力与断层构造应力耦合诱发冲击地压风险。以梁宝寺矿5304冲击危险工作面为工程背景，根据Anderson断层力学模型推导出滑移失稳判据μm结合现场地应力测试数据分析；基于弹性力学理论构建采动影响下断层围岩解析模型；运用FLAC3D软件大变形和interface功能，研究工作面推进过断层过程中应力分布、断层面滑移特征。研究结果表明：工作面前方20 m出现超前支承应力集中，当工作面与断层间距5 m时峰值应力达58.871 MPa（应力集中系数2.43）。断层滑移量随着二者距离缩短而递增，在推进至断层时剪切滑移达到峰值；基于上述研究，现场采取爆破切顶卸压措施，并通过微震监测、钻孔窥视联合验证，监测数据均未超预警阈值，表明卸压控制断层活化滑移风险。研究结果可为工作面过高角度断层冲击地压防治提供参考。
Abstract:
In order to mitigate the rockburst risk induced by the coupling effect of mining-induced stress and fault tectonic stress when the working face passing through fault zones,this study takes the 5304 working face with high rockburst risk in Liangbaosi Coal Mine as a case study.Based on the Anderson fault mechanics model,a slip instability criterion μm was derived and combined with on-site in-situ stress measurement data for analysis.An analytical model of the rock surrounding the fault under mining disturbance was established using elastic mechanics theory.The large deformation and interface functions of FLAC3D software were employed to investigate the stress distribution and fault slip characteristics during the advancement of the working face across the fault.The results indicate that an advance abutment stress concentration occurs 20 m ahead of the working face,with a peak stress of 58.871 MPa (stress concentration coefficient of 2.43) when the working face is 5 m from the fault.The fault slip displacement increases as the distance decreases,reaching its maximum shear slip when the face advances to the fault.Based on these findings,roof-cutting blasting for pressure relief was implemented on site.Validation through microseismic monitoring and borehole imaging showed that monitoring data remained below the warning thresholds,demonstrating the effectiveness of the pressure relief measures in controlling the risk of fault activation and slip.The findings provide a valuable reference for rockburst prevention when a working face traverse a high-angle fault.
