上向水平分层充填法分段高度探讨

Discussion on the sublevel height of flat-back cut-and-fill method

上向水平分层充填法的分段高度应根据矿岩的稳定情况、采场结构类型、中段高度以及出矿设备等因素来确定,以达到降低采切比、提高生产效率、减少采矿成本的目的。本文通过对获各琦铜矿分段高度的探讨,实现上向水平分层充填法分段高度优化,为其它类似矿山提供借鉴。

The sublevel height of flat-back cut-and-fill method should be determined according to the stability of mine rock,the type of slope structure,the level height and ore drawing equipment,and it can decrease the mining-cutting ratio,improve production efficiency and reduce the mining cost.Through the discussion of the sublevel height of Huogeqi Copper Mine,the optimum sublevel height of flat-back cut-and-fill method was obtained,which can provide use for reference for other similar mines.
