摘　　要：文章以井下开采巷道围岩应力变化为研究对象,在前人研究基础上提出了煤岩体弹性、塑性及脆性本构模型,并从煤岩体微观单元和宏观材质2个方面进行计算机仿真模拟,分析了裂隙扩张的本质原因和剪切局部化对煤岩体应力的影响,并验证了仿真结果的有效性。Computer simulation technology in coal mining is widely used in the field of. Based on the underground mining roadway surrounding rock stress changes as the research object, on the basis of previous research put forward coal rock mass elastic, plastic and brittle constitutive model, and the computer simulation from two aspects of microcosmic and macroscopic unit of coal and rock material, analyzes the influence of the essential reason crack expansion and shear stress on coal the rock, and verify the validity of simulation results.
