矿山压力对底板破坏深度监测研究
Based on the analysis of roof water-inrush source,the relationship between water-inrush from roof and underground pressure and rockburst was revealed.
在分析4煤层开采顶板突水水源的基础上,揭示了矿山压力、冲击地压同顶板突水之间的关系,探讨了煤层开采过程中顶板突水对促进冲击地压形成的影响作用机理;基于物理流变学和断裂力学理论,提出了砾岩粒间隙中的水流失导致砾岩粒界面附近多层次应力局部集中,造成砾岩产生新的断裂,形成多层次冲击地压,促进顶板斑裂线扩展的机制,阐明了冲击地压和顶板突水互为影响的因果关系,从理论研究和现场监测2个方面得出了华丰煤矿4煤层开采深度大于520 m时容易形成冲击地压的结论。
