摘要
通过本矿原设计护巷煤柱宽度对于巷道应力分布的影响,结合本矿实际,应用计算机模拟(FLAC),模拟并分析了不同煤柱宽度及巷道围岩在回采期间的应力分布及变形情况,获得了不同的煤柱宽度巷道围岩在回采期间的力学特征,为煤柱宽度的合理留设、支护参数选择等提供理论依据。
Aiming at the effects of the originally - designed chain pillar on stress distribution of roadway, the author has applied computer simulation （ FLAC） to analyzing the stress distribution and deformation of chain pillars of different width and adjoining rocks in the course of extraction, which helps to obtain mechanical characteristics of adjoining rocks with different pillar widths and provide theoretical basis for the rational arrangement of the pillar width and the selection of support parameter.
