为了解决亨健煤矿村庄下压煤的开采问题,采用超高水材料对工作面采空区及主巷进行了充填,工作面副巷通过高水材料巷旁充填进行沿空留巷,并通过对采空区补充充填提高了充填率。工程实践结果表明:袋式充填开采技术不仅有效地控制了上覆岩层的破坏及移动,工作面矿压显现也得到了极大的减缓,同时工作面副巷也得到了很好的留巷效果。 In order to solve the problem of coal mining under Hengjian coal mine, ultra-high water materials were used to fill the goaf and the main lane of the working face. The auxiliary lane of the working face was gob-side entry retained by the high-water material, Filling the mined area to improve the filling rate. The results of engineering practice show that the technology of bag filling and mining not only effectively controls the destruction and movement of the overlying strata, but also greatly reduces the strata pressure of the working face, and also has a good effect of retaining roadway in the working face. .
