摘要
在铜绿山矿井下残留矿柱回采中 ,采用超前拉槽、分次落矿、梯段式推进等新颖独特的采矿工艺技术 ,圆满地解决了残矿回收过程中技术与经济难于统一的问题 ,取得了良好的技术效果和显著的经济效益。该项技术具有很高的借鉴价值和广阔的推广应用前景。
In the exploitation of underground residual pillars at T onglushan Mine,some noval and unique mining techniques such as advance cutting ,sequential slice-caving and bench-pushing forward etc. were used to solve the p roblem of technique and economy unification satisfactorily in the process of re sidual pillars recovery.Some good technical effect and obvious economic benefit were achieved.This technology is possessed of better referential value and wide application prospect.
