摘要
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 mine under a village,super high water material was used in goaf and main roadway,and high-water material was used in auxiliary roadway of Hengjian coal mine. Besides,supplementary filling was carried out to guarantee the filling rate. The engineering practice shows that bag type filling technology can effectively control overlying rock and reduce mine strata pressure. What′s more, tangible gob-side entry effect can be seen in auxiliary roadway.
