摘要
崩落采矿法是金属矿山地下开采应用较多的一种高效采矿方法,覆岩下底部放矿损失贫化大是该采矿法的一个特点。文中分析总结了覆岩下底部放矿损失贫化产生的因素,即松散矿石的物理力学性质、放矿口的结构及尺寸、矿体的厚度及倾角、放矿管理等,可为应用崩落采矿法矿山损失贫化管理提供借鉴。
Caving method is a high efficiency mining method widely used in underground metal mines. While it is a characteristic of the method that the loss rate and dilution rate is high. The paper carried out a factor analysis on loss and dilution of overburden strata bottom ore-drawing. And the most influential factors were the physical mechanic property of broken ore, structure and dimension of drawhole, thickness and inclination of orebody and ore drawing management. It is a good reference for loss and dilution management in mines which apply caving method.
