似膏体管道自流充填技术在孙村煤矿的应用

摘要

介绍了孙村煤矿综采工作面的似膏体管道自流充填技术,论述了其充填步距、充填工艺机理流程、充填措施及充填效果,实现了充填开采降低地面污染、减少地表下沉、提高资源回收率、延长矿井服务年限的目的,该技术意义重大,具有推广应用价值。%The gravity-flowed paste-like filling technology of fully-mechanized mining face in Suncun coal was described in this paper.The filling step,the mechanization process of the backfill technique,filling measures and backfill effect were stated in the paper.The backfill mining method was not only beneficial to reduce the ground pollution and avoid surface subsidence,but also improve the coal recovery rate and extend the mine service time.This method had a great significance and high applicable value.
