摘要
采掘工程破坏了断层围岩原有的应力平衡状态,使断层发生滑移,严重时会引发冲击地压。为了研究采掘工程对断层的影响,采用UDEC数值模拟软件,分别模拟了断层下盘和断层上盘煤层开采,分析采掘工程对断层面滑移的影响。研究表明:距断层面相同距离时,下盘开采较上盘开采对断层滑移量的影响更大,下盘开采较上盘开采更容易发生断层冲击地压。
Mining engineering destroys the equilibrium state of original fault rock stress , causes fault slip and lead to rock burst when it is serious. In order to study the impact of mining engineering to fault, by using UDEC nu- merical simulation software respectively simulate the footwall mining and hanging wall mining of fault. Analyzes the impact of mining engineering to fault. The researches show that when the same distance from fault plane, footwall mining influence to fault slip is greater than hanging wall mining, and more easily happen fault rock burst
