中文摘要：

随着煤炭开采向深部发展,围岩地应力也越来越大,巷道断面积、形状的选择对于降低围岩集中应力和巷道变形尤其重要.首先采用复变函数方法构建矩形巷道的复应力函数,得出矩形巷道的围岩应力计算公式,从理论上分析了矩形巷道围岩应力的主要影响因素;然后以某一具体矿井的生产地质条件为背景,应用FLAC5.0数值模拟软件模拟分析不同巷道尺寸时的围岩应力分布情况,提出了巷道开挖后的支护对策.

英文摘要：

With the deep mining development of coal mining, ground stress is more and more high in surrounding rock, and it is especially important that the shape and section area of roadway is optimally selected for decreasing local stress concentration and deformation of surrounding rock. First of all, the complex stress function was constructed by complex function method, calculation formula was obtained for surrounding rock stress of rectangular tunnel, and its main influence factors was analyzed. Then, based on a specific productive geological conditions, distribution of surrounding rock stress of different roadway dimension was analyzed by FLAC5.0 numerical simulation software, and the supporting measures of excavated roadway was put forward.
