Abstract:: Aiming at the problem that inappropriate process parameter control of surface horizontal well fracturing under mined roadway conditions easily induces secondary damage to roadways, a construction parameter optimization method considering both fracturing effect and roadway stability was established with a working face in Zhaoxian Coal Mine of Yonglong Mining Area as the engineering background. Multi-software collaboration including MFrac Suite, Abaqus and UDEC was adopted to conduct fracture propagation simulation, fracturing safety boundary determination and surrounding rock deformation control analysis, respectively, and a pre-treatment evaluation was performed on the rock burst prevention effect of hydraulic fracturing.The results show that the optimized parameters are an injection rate of 14 m3/min and a single-stage fracturing fluid volume of 1400 m3. Under these conditions, the fracture network can completely cover the working face and remain outwardly separated from the boundary of roadway disturbed fractures, with the surrounding rock deformation meeting the control requirements. Hydraulic fracturing transforms the overburden strata from integral subsidence to segmented failure by altering the structural integrity of overlying strata, resulting in a significant reduction in the maximum subsidence and the peak value of advanced abutment pressure.Field engineering applications demonstrate that microseismic monitoring during fracturing verifies complete coverage of fractures over the entire working face. After fracturing, during coal mining, the microseismic energy, event frequency, maximum energy and average weighting interval decrease to 3%, 10%, 6% and 23.26% of those without fracturing, respectively; the average weighting duration increases to 13.64% of that without fracturing, and energy is released uniformly with high frequency and low magnitude. The characteristics of secondary roadway damage during fracturing are controllable.This study reveals that the essence of rock burst prevention via hydraulic fracturing lies in the collaborative regulation of stress and energy through structural weakening. The research findings can provide a technical reference for rock burst control in coal mines under similar working conditions.
