摘要： 对冲击倾向性的研究能有效地预防冲击地压的发生，对于煤矿的开采工作具有重大的实际意义。在全面、系
统归纳总结分析保安煤矿矿井已有地质资料的基础上，现场井下进行15 号煤层的取样。对煤样的单轴抗压强度、动态破
坏时间、冲击能量指数、弹性能量指数等冲击倾向性指标进行了试验和分析，综合判定15 号煤层的冲击倾向性属于I
类，无冲击倾向性。以上述研究结果为基础，结合保安煤矿15 号煤层的实际生产条件，为该煤层开采延伸工程中的矿压
安全管理提供技术依据。

Abstract: The research on impact tendency can effectively prevent the occurrence of rock burst, which is of great practical significance
for coal mining. On the basis of comprehensive, systematic and inductive analysis of the existing geological data of Baoan
Coal Mine, the coal rock samples of No.15 coal seam were collected underground. The impact tendency indexes of coal samples
were tested and analyzed, such as uniaxial compressive strength, dynamic failure time, impact energy index and elastic energy
index. It was comprehensively determined that the impact tendency of No.15 coal seam belonged to class I and had no impact
tendency. Based on the above research results, combined with the actual production conditions of No.15 coal seam in Baoan Coal
Mine, the technical basis for the safety management of mine pressure in the extension project of the coal seam was provided.
