摘要
根据某铁矿地质和开采条件,采用PHASE 2D有限元软件建立数值模型,研究多次重复开采影响下覆岩的塑性区发展及地表变形规律。研究结果表明,重复开采下倾斜矿体覆岩及地表呈非对称破坏及变形规律。
Based on the actual geological and mining conditions of an iron mine, a numerical model is established using PHASE 2 D. The development of plastic zone in overburden, and ground movement under repeating mining are studied. The results show that asymmetric development of plastic zone and surface displacement is observed for the inclined orebody under repeating mining.
