摘　　要： 根据艾维尔沟煤矿实际工程地质状况,采用Midas软件建立缓倾斜无巷旁充填沿空留巷模型,针对800 mm厚混凝土墙和锚柱+矸石混凝土墙2种方案进行模拟计算。研究结果表明:在保证留巷稳定性的情况下,2种方案的巷道变形量控制在4~30 mm。综合煤炭回采率、施工进度、人力成本的情况,应采用锚柱+矸石混凝土墙的无巷旁充填方案。 Based on the actual project geological conditions of Aiveiergou mine,uses Midas software to build beside the gently inclined roadway without filling gob model and conducted simulations on 800 mm thick concrete walls and columns +gangue concrete wall. The results show: in the case to ensure the stability of the left lane roadway,controlled deformation of the two programs is 4~30 mm and lateral stress deformation is two times,vertical deformation little change. In the case of coal recovery rate,construction progress and the human cost,no lane filling solution of anchor column +gangue concrete wall should be adopted.
