基于计算机仿真技术的煤岩体的弹塑脆性本构模型研究

Reserch on Elastic-plastic Brittle Constitutive Model of Coal and Rock Based on Computer Simulation Technology

在煤矿安全生产事故中,煤岩体事故是最常见的事故之一,是矿山安全生产中不容忽视的重要问题,给矿山的安全生产带来隐患,也将直接威胁作业人员的生命安全。文章首先概述了弹塑脆性本构模型与煤岩体变形破坏规律,对煤岩体的工程背景与底板巷道合理位置进行了确定,然后对煤岩体变形规律进行了计算机仿真数值模拟。

In the coal mine production safety accidents, coal and rock accident is one of the most common accidents, will be a direct threat to the lives and safety of the operating personnel to the mine production safety and security is an important issue can not be ignored in the mine production safety. The paper first outlines the elastic-plastic brittle constitutive model of coal and rock deformation and failure of the law, coal and rock engineering background and floor rock reasonable position to determine the numerical simulation of the computer simulation, then the coal and rock mass deformation law.
