充填开采既是"三下"压煤开采的常用技术途径,又是煤矿绿色开采技术体系的重要组成部分。在简述我国充填开采技术的基础上,对现代煤矿充填技术应用进行了新的分类,对泵送高浓度胶结材料充填、巷道迎头抛矸机胶带充填、采空区架后刮板输送机漏矸充填、混凝土膏体材料充填4种充填技术应用进行了介绍,并分析了现行煤矿充填技术的缺陷及发展方向。
Stowing mining is common technology approach of mining coal under river,railway and building,and is also important component of green mining technology system On the basis of introducing Chinese stowing mining technology,this paper re-classified modern stowing technologies 4 stowing technologies including stowing of cementitous material with high consistency by pump,refuse stowing by belt in roadway,stowing by scraper behind support,stowing with concrete paste material were introduced The shortcomings of current stowing technologies and development tendency were analyzed as well
