顶板诱导崩落机理及其在铜坑矿的应用研究
首发时间:2005-02-02
摘要:本文运用突变原理分析了基于矿山连续开采空区顶板处理的诱导崩落机理,分析各种扰动因素,如采场顶板围岩的力学性质、采空区的面积、拉应力作用区范围和大小等对采场顶板失稳时的影响,并针对铜坑矿的地质力学模型,运用三维有限元数值模拟研究了在铜坑矿非重叠区域下连续采矿诱导崩落技术的应用。

STUDYING THE INDUCTION CAVING ROOF AND APPLYING IN THE TONGKENG MINE
Abstract:In the paper, on the base continues mining, the catastrophe mechanism of induction caving is studied in the mined volume roof, and then these factors are studied such as the mechanical property of the surrounding rock, the area of the gob, the scope and dimension of tensile stress. Then applying the principle and the three dimensional finite element method, the mechanical model is built, the results show that the induction caving processing parameter is suit in the Tongkeng Mine.
Keywords: Handling Roof Induction Caving Catastrophe Mechanism Finite Element Method
