本文对地下采煤引起的岩体变形,破坏问题,应用概率计算、理论分析方法进行了分析。由于岩体的破坏是随地下采煤时间等因素而变化的,故文中推导了与时间相关的岩体破坏概率公式,以用于研究岩体移动、地压活动规律等问题。
In this paper, the deformation and damage of rock mass caused by underground coal mining are analyzed by using probability calculation and theoretical analysis. Since the failure of rock mass changes with the time of underground coal mining, the time-dependent probability of failure of rock mass is deduced to study the problems such as the movement of rock mass and the law of underground pressure.
