矿井“采-选-充”一体化开采技术

Integrated mining technology of "mining-selecting-filling"

探索一种"三下"压煤开采技术,并详细阐述介绍"采-选-充"一体化开采技术的原理及内涵,分析其存在的技术重点和难点,研究其高效运作的布置方式,并对"采-选-充"一体化技术应用后,采动影响下的地表沉陷进行了现场实测,验证了"采-选-充"技术的可行性,为解决"三下"压煤开采提供技术解决办法,为地表沉降的防治、矸石废料的处理以及相似赋存条件下的煤炭资源的开采提供理论借鉴。

＂Three unders＂in coal mining technology was explored in this paper, principle and connotation of ＂mining-selecting-filling＂ technology was elaborated, as well as existing key and difficult points. At the same time, its efficient operatioanal arrangement form was researched. After application of ＂mining-selecting-filling＂technology, subsidence under the influence of mining processed field mearsurement to ensure its feasibility, which not only provided technical solutions to ＂three＂coal mining, but theoretical reference to prevention of ground surface seetlement, dispose of gangue waste and mining of coal resources under similar occurrence conditions.
