富家矿下向高分层机械化胶结充填采矿研究

Study on mechanical cementing mining with high undercut in Fujia mine

富家矿转入深部开采以后 ,矿体变小 ,采场转层次数频繁 ,生产能力降低。通过扩大采矿进路断面 ,引进铲运机取代电耙出矿 ,改变采准开拓方式 ,应用“少熟料粉煤灰矿渣水泥”做胶凝材料 ,取得较好经济效益。

After entering deep mining in Fujia mine, the orebody becomed small, stope layer transition increased, and productive capacity decreased. Through enlarging drift section in stope, replacing scraper with load-houl-dump, changing stope development way, and applying fly ash slag cement with less chinker as binding material, good effect is obtained.
