摘要
山西阳城阳泰集团竹林山矿1831工作面直接顶为深部易风化复合顶板,煤岩体的构造应力场比较复杂,以1831工作面的地质条件为背景,利用udec计算模型,对不同深度下巷道应力场的规律进行探究,得出一定结论,对巷道的支护参数选择提出合理化建议。
The roof of 1831 working face of Zhulin mine of Shanxi Yangcheng Yanyai Group, is deep weathering composite roof, and the stress field of coal-rock mass is very complex. Considering the geological conditions of 1831 working face, using uvec calculation model, the paper probed the law of the stress field of roadway under different depth, and gave many rational suggestions for roadway supporting parameters selection.
