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 coal mine safety accident, coal and rock mass accident is one of the most common accidents, which is an important problem that can not be ignored in mine safety production. It brings hidden dangers to mine safety production and also directly threatens the life safety of workers. Firstly, the brittleness constitutive model and the deformation and failure of coal and rock mass are summarized. The engineering background of coal and rock mass and the reasonable position of floor roadway are determined. Then, the deformation of coal and rock mass is simulated by computer simulation.
