| 摘 要： | 陷落柱突水事故在我国煤矿时有发生,但其导水机理至今仍不十分明确。为分析在弱径流条件下陷落柱柱体活化导水的机理,可用弹性理论求出在自身重力、周边地应力和地下水压力作用下的陷落柱柱体内的应力分布。根据这些应力分析,分别采用G riffith理论、极限平衡理论和库仑准则,可以推导出柱体的关键层和非关键层的活化导水的判据,并据此判据分析了影响陷落柱柱体破坏导水的有关因素。

| Abstract: | Water inrush from karst collapse columns frequently happened in china's coal mines,however the mechanism is not very clear.In order to analyze the mechanism of karst collapse column activating and to conduct water under weak runoff state,elastic and plastic theory can be used to seek the solutions of the stress of columnar by the gravity,the pressure of ground water and the other stress around.According to these stress analysis,using Griffith theory,Limit balance theory and Coulomb criterion,criterions of columnar activating to conduct water can be made out,and the factors influencing the transmissibility of columnar also can be analyzed further. |
