饱水状态对岩石冲击倾向性影响的研究

Influence Study on Burst Potentiality to Rocks under Water-saturated Condition

摘要:

取菏泽赵楼煤矿岩样进行了饱水前后冲击倾向性指标的对比试验，研究发现饱水状态对岩样弹性能量指数影响明显，动态破坏时间和冲击能量指数亦有影响。对于不同水稳性特征的岩石，饱水前后的冲击倾向性存在明显差异。

Abstract:

By choosing rock samples from Zhaolou coal mine in Heze city, contrast test of burst potentiality before and after water saturated condition, it is found that it has great impact on elastic energy index under water saturated condition. Burst energy inde
