浅谈上向水平分层充填采矿法在获各琦铜矿的应用经验

Brief discussion about application experiences of upward horizontal cut-and-fill stoping in Huogeqi Copper Mine

随着国家对矿山行业的安全、环保采矿要求越来越高,充填采矿法在我们国内的矿山被广泛使用。这种方法对损失贫化指标较小、灵活性大,可根据矿石及岩石性质调整采准和回采方式,对高品位或贵金属资源的回收有更大的指导意义,同时能为矿山控制井下地压、防止围岩崩落、减少尾砂排放量、提高矿石回采率等优点。本文浅谈一下上向水平分层充填采矿方法在获各琦铜矿实际使用后得到的微足技术管理经验。

As our country rise the demand of safety and environmental protection of mining higher and higher, filling mining method has been widely used in mines in the country. This stoping method is flexible; will effectively reducing loss dilution rate; and also can be adjusted according to the character of ore and rock during process. This method also has great significance result on high grade and precious metal recycling. At the same time this method can also control downhole pressure, prevent the surrounding rock caving, and reduce emissions of backfilling materials, improve the ore recovery rate, etc. In this article will briefly talk about few application experiences of upward horizontal cut-and-fill stoping in Huogeqi Copper Mine.
