摘　　要：为保证冲击地压孤岛仰采综放工作面的安全回采,从影响冲击地压多种因素和数值模拟对常村煤矿MZ21010工作面的冲击危险性进行分析评价,根据“三限三强”的防冲原则,优化各项防冲措施参数,对工作面实施综合防冲措施。从已经回采的三个月各项监测指标分析,工作面采取的防冲措施取得了较好的效果。In order to ensure the safe mining of the fully mechanized caving face with isolated island upward mining of rock burst,the risk of impact in the MZ21010 working face of Changcun Coal Mine is analyzed and evaluated from various factors and numerical simulation that affect rock burst.According to the principle of"three limits and three strengths"for rock burst prevention,the parameters of various rock burst prevention measures are optimized,and comprehensive rock burst prevention measures are implemented for the working face.Based on the analysis of various monitoring indicators in the three months of mining,the rock burst prevention measures taken at the working face achieve good results.
