摘要
以沽源煤矿主运输大巷实际地质条件,煤岩体实验室力学试验为基础,利用有限差分数值模拟软件FLAC^(3D)分析主运输大巷在不同底鼓治理措施下底板围岩特征,重点比较各措施下底鼓量,并以此为依据优选出主运输大巷最佳的底鼓治理措施为原支护方案加底板锚(锚杆或锚索)注。
Basing on the actual geological conditions of main haulage roadway in Guyuan coal mine and the laboratory mechanics tests of coal or rock, finite difference numerical simulation software FLAC3 Dwas used to study the destruction of surrounding rock, stress and deformation characteristics in roadway floor under different floor heave control measures, through comparison of the various floor heave control measures, the most appropriate control measure of floor heave in main haulage was selected.
