摘要
详细阐述了斗南锰矿嘎科矿段现有的3种采矿方法存在的缺点,并且在矿体赋存条件复杂的采场采用联合式采矿法进行采矿作业试验,最终取得了良好的技术经济效果,试验证明:联合式采矿法实质上是对同一采场的不同部位都选用了最佳的采矿方法的组合。
DouNan manganese expounds the existing honk in ore mining method of three kinds of faults.It has complicated burring conditions in the complex combinations of stope mining method which was adopted to mining.The final test made good economic result proves that the mining method,and the joint type is essentially the same stope in different parts of the optimal selection of all mining method that combined.
