武钢程潮铁矿西区放顶工程顶板地压问题的计算机模拟
Computer Simulation of Underground Stress on Top during Top-collapse Engineering at Western Part of Chengchao Iron Mine
【摘要】 采用有限单元法对程潮铁矿西区放顶过程中地压重新分布的规律进行分析,为矿山正确地确定回采顺序和对地压进行预测、管理提供了理论依据。
【Abstract】 Finite element method is used to make an analysis of the underground stress redistribution at the western part of Chengchao Iron Mine during top-collapsing process, and a theoretical basis has been provided to determine correct sequence of caving and forecast and control the underground stress.
