摘要
文中针对南庄矿可采储量逐渐枯竭的现象,为了合理开发煤炭资源、延长矿井服务年限、提高矿井煤炭资源回采率,就15#煤八采区六联通巷以西、七联通以东大巷煤柱回收技术进行研究。综合分析了煤柱回收的可行性,比选确定了煤柱回收方案,以及煤柱回收的效益。
According to the phenomenon of coal exhausted in Nanzhuang coal mine,in order to develop reasonably the coal resources,extend the coal mine service life,and improve the mine coal resource recovery rate,pillar recovery technology on the 15# coal mining area coal was carried out. Coal pillar recovery technologies in the west of Six Unicom Lane and the east of Seven Unicom in No. 8 coal mining area in 15 # coal were studied. The feasibility of coal pillar recovery was analyzed synthetically,and the benefit of coal pillar recovery scheme and the coal pillar recovery schemes were determined by comparison.
