缓倾斜矿体下三角矿石回采方案研究

摘要院随着我国采矿业的发展，焦家金矿的开采技术得到了很大的提升。焦家金矿的采矿方法分为上向水平分层进路充填采矿法和下向水平分层进路充填采矿法，进路采矿至主断裂带时，对下三角矿石进行回收处理。为减小下三角矿石损失，增加矿石回收率，对矿石品位较高的下三角矿石研究制定单独回收方案。方案中下三角矿石分两步进行回收，该方案可以将下三角矿石回收率提高14.8%。降低资源损失，提高经济效益。

Themining method of Jiaojia gold mine is divided into the upward horizontal slicing and filling mining method and the downward horizontalslicing and filling mining method. The lower triangular ore is carried on the recycling when mining to the main fault zone. To reduce the lossof lower triangular ore and increase the ore recovery this paper studies and formulates the separate recycling scheme of the high ore gradelower triangular ore. The recycle of the lower triangular ore can be carried out in two steps in this scheme which can increase the lowertriangular ore recovery by 14.8% reduce resource loss and improve the economic benefit.院缓倾斜矿体 下三角 回采 方案研究Key words gently inclined ore body lower triangular mining scheme research中图分类号院TD853 文献标识码院A 文章编号院1006-4311（2014）27-0309-02
