摘要
Abstract
Taking the 41106 island-like working face of Shandong Liangzhuang Mining Co.,Ltd.as the research object,this study systematically investigates the influential patterns of hazardous factors including geological structures,goaf distribution,and coal pillar stress concentration during mining under rock burst risks,employing comprehensive methods including theoretical analysis,numerical simulation,and engineering analogy.FLAC3D numerical simulation was utilized to analyze the evolution characteristics of advanced abutment pressure during the mining process of the working face.Combined with strata pressure monitoring data from adjacent working faces,the adaptability of support strength for the working face brackets was verified.The research indicates that the 41106 working face,affected by fault cutting and three-side goaf conditions,exhibits significant stress concentration in coal pillar areas,with potential instability risks in fault-related coal pillars.The study demonstrates that optimizing coal pillar width and enhancing support measures can effectively reduce the probability of rock burst occurrences.关键词
