摘要

摘要: 在对冲击地压显现全面调研的基础上,分析了冲击地压的防控现状与发展趋势,提出了高应力与高能量冲击地压的工程缺陷防控方法。针对冲击地压煤层的工程特性,进行了缺陷的定义与分类,详尽地论述了工程缺陷对冲击地压防控的力学机制;分析了含有缺陷介质体的冲击危险煤层应力分布特征,并结合实例详细阐述了工程缺陷防控冲击地压的机理及具体应用情况,对缺陷体的能量释放范围和程度进行了数值模拟验证,在深部与强冲击能量区域冲击地压治理方面获得了一定的成效。

Abstract: Based on the complete researches on rock burst, the prevention and control situations and development tendency of rock burst are analyzed. The prevention and control idea of high stress and high energy rock burst is put forward. Defect is defined and classified as regards the engineering characteristics of rock burst seams. The mechanical mechanism that rock burst is prevented and controlled by engineering defect is described. Stress distribution of dangerous coal seams with defect media is analyzed. The specific application of mechanism that rock burst is prevented and controlled by engineering defect is elaborated through some projects, numerical simulation of range and degree of energy release is carried out. At the same time, some advances in the prevention of control of rock burst in deep and high impact energy areas are achieved.
