摘要/Abstract

摘要： 顶板垮落是金属矿山地下开采过程中较为严重且常见的工程灾害之一，针对中钢苍山铁矿层状顶板岩石特性，分析了岩层破坏过程和各因素的影响规律，利用FLAC3D软件建立三维数值力学分析模型，对顶板进行应力应变分析，通过数值分析软件研究50～300 m埋深时，顶板随不同的岩层分层厚度、不同的埋深等因素而变化的破坏规律。

Abstract: Roof collapse is one of serious and normal engineering disaster in the underground exploitation process of metal mine. Aiming at the rock properties of layered roof of Sinosteel Group Cangshan Iron Mine, destroy process of strata and influence law of each factors were analyzed. 3-D numerical mechanical analysis model was established by using FLAC3D software. The stress-strain analysis was done on roof, changing destroy law of roof in condition of different delamination-terrane thickness and buried depth and other factors under depth of 50~300 m were studied through numerical analysis software.

Key words: Hard Rock, Layered structure roof, Mechanical structure model, FLAC^3D
