| 摘 要： | 为了搞清煤体强度对冲击地压防治的影响，通过试验研究了千秋煤矿二号煤层试样单轴抗压强度与冲击能量指数之间的关系。结果表明煤样的冲击能量指数与单轴抗压强度呈较显著的线性关系。煤样的浸水软化试验证明煤的冲击能量指数随单轴抗压强度降低而减小。降低煤层的煤体强度可以消减煤的冲击倾向性，是防治冲击地压发生内因的有效措施。

| Abstract: | In order to understand the coal strength affected to the mine pressure pumping prevention and control,the experiment study was applied to the relationship between the uniaxial compressive strength of the sample from No.2 seam and the bumping energy index in Qianqiu Mine.The results showed that the bumping energy index and uniaxial compressive strength of the coal sample have a obvious liner relationship.The water immersion softening test of the coal sample showed that the bumping energy index would be reduc... |
