倾斜中厚低品位铁矿采矿方法选择与优化研究

摘要

On the basis of fully analysis of many influence factors of mining method,the mining methods for complex low grade iron mine are selected and optimized by using engineering analogy,empirical design calculation and the test method of the stope Then the low cost, high efficiency grail area, high layer back-filling method which ramp into the stope directly for this mode of ore-body is established, and some mining problems such as high stripping ratio, low efficiency mining for this type of ore body is solved.%在充分分析影响采矿方法诸多因素的基础上,采用工程类比、实证设计计算和采场试验的方法,对苍山复杂低品位铁矿采矿方法进行了比选和优化,确定了适合该矿体赋存状态,低成本、高效率、斜坡道直接进采场的大盘区高分层充填采矿方法,解决了该类矿体条件下高采切比、低效率回采问题.
