摘要
结合矿井一采区工况条件制定了五种充填方案,通过对各方案技术特点的比较,综合对回收率、充填工艺和地表变形情况等的分析,最终选用巷道不等强完全充填开采方案。
Five kinds of filling schemes are formulated according to the working conditions of the first mining area in the mine.By comparing the technical characteristics of the schemes and analyzing the recovery rate,filling technology and surface deformation,the unequal-strong fully filling mining scheme is finally selected.
