一、概述阶段自然崩落法是一种利用矿岩本身的裂隙、节理或地质构造,在自重应力的作用下,使矿石自行破碎和崩落的采矿方法。它的主要优点是,采准切割比小,回采工作基本上不用凿岩爆破,采空区能及时得到处理,因而采矿成本 I. Overview Stage The natural caving method is a mining method that utilizes the fracture, joint or geological structure of the ore rock itself to make the ore break and fall by itself under the effect of self-weight stress. Its main advantage is that the quasi-cutting ratio is small, basically no drilling blasting mining work, goaf can be treated in time, so mining costs
