地下金属矿山目前广泛地使用着复盖围岩下放矿的分段和阶段崩落采矿法,这对促进和实现矿山强化开采,担负着重要的作用。然而,该方法是在复盖废石下崩矿和放矿的,崩落矿岩的直接接触,是导致矿损贫化的重要原因。因此,我们必需对崩落采场的放矿进行研究,探讨崩落矿岩的流动规律,作为确定采场合理结构参数、改革放矿工艺
At present, the underground metal mines are widely used to cover the sub-rock caving and subsidence mining step by step, which is to promote and achieve mine enhanced mining, plays an important role. However, this method is a major cause of mineralization depletion due to the direct contact of caving ore that collapses and drains over the covered waste rock. Therefore, we must study the ore caving in the caving area, discuss the law of the flow of the caving ore, determine the reasonable structural parameters of the stope, reform the ore drawing process
