LFM轻型充填材料在运河煤矿沿空巷道的应用

The Application of LFM Light Filling Materials Using in Along Roadway in Yunhe Coal Mine

运河煤矿沿空巷道封闭一直采用喷浆方式封闭沿空侧围岩,喷浆灰利用率较低,喷浆工作受运输、工艺限制,占用人员较多,为此,运河煤矿不断探索新工艺、新技术,采用LFM轻型充填材料代替喷浆灰封闭沿空巷道,简化了生产工艺,提高了材料利用率,降低了人工投入,最终达到了提高劳动效率的目的。

The seal of along roadway in Yunhe Coal Mine is use guniting method to seal the surrounding,the utilization ratio of guniting ash is low and guniting is limited by transportation and skill,the number of employee is high.In order to solve this problem,Yunhe Coal Mine con- stantly explore on new skill and technology,using LFM light filling material replace the guniting seal method can simplify the production skill, improve the utilization ratio of material and reduce the number of employee and finally reach the point of improve the work efficiency.
