赵各庄矿深部回采巷道围岩变形规律的数值模拟研究

The Numerical Value Simulation Study of the Transmutation Rule of Wall Rock in Deep Return Picks Laneway at Zhao Gezhuang Mine

针对深部回采巷道的围岩变形规律而采取针对性的治理措施,改善巷道的支护与维修现状,利用连续介质显式有限差分计算机软件FLAC3D对综采放顶煤工作面的回采巷道围岩变形规律进行了数值模拟研究,并根据其数值模拟结果采取了超前加固支护,有效地控制了深部软岩巷道支架变形,降低了巷道的维修量,对深部矿井开采有一定指导作用。

The pertinent neaten measures are adopted for the numerical value simulation study of the transmutation rule of wall rock in deep return picks laneway. The laneway＇ s shoring and servicing status quo are improved. The FLAC3D software are utilize to study the numerical value simulation of the transmutation rule of wall rock in deep return picks laneway. The neaten measures are taken based on the study result. The bottom drum of deep wall rock laneway and the transmutation of bracket are controlled availably. And the maintain quantity of the laneway are reduced greatly. All of these have certain supervise action to the deep mine exploitation.
