本文对北京矿务局大安山矿702机采面的矿压规律进行了空间物理模拟研究和数值模拟研究,得出了该工作面直接顶、老顶的冒落及破坏规律。经现场的工业试验证明,这些规律对工作面的顶板管理具有一定的帮助,简化了工作面的顶板管理过程。
In this paper, the geophysical simulation and numerical simulation of the mining pressure of the working face of Daianshan Mine 702 in Beijing Mining Bureau are carried out, and the laws of the caving and failure of the direct top and the top of the working face are obtained. The field test proved that these laws have some help to the roof management of the working face and simplify the roof management process of the working face.
