Abstract: Aiming at the challenges of support technology and the potential high risk of collapse in the roadway when crossing faults in coal mine tunneling operation,the deformation mechanism of surrounding rock when crossing faults in the tunneling face is systematically explored,and the corresponding control technology strategy is analyzed. Based on the theoretical framework,we analyzed the stress environment characteristics of the area adjacent to the fault,used numerical simulation technology to analyze the stress distribution and displacement changes of the surrounding rock when crossing the fault and the conventional roadway with different support schemes,and formulated the optimized support scheme for the tunneling face crossing the fault. The engineering application effect shows that the implementation of the integrated support strategy of “anchor combined with anchor cable”,supplemented by the installation of additional angle anchors to enhance the overall effectiveness of the support system,can realize the effective control of the rock body around the tunneling face through the fault.The results can effectively improve the stability and bearing capacity of the support system,and curb the excessive deformation and potential destabilization of the surrounding rock.
