分層崩落采矿法是一个较新的采矿法,也是一种适用条件较寬的采矿法,对价值较高、形状较复杂的有色金属矿床更具有特別有利的适用条件。因此它在我国有色系統矿山中采用的比重不断增長。尤其是在目前木材供应特別紧張的情况下,各采用分層崩落法的矿山,如何解决分層崩落怯的大量木材消耗問題,已成为急待解决的問題。本文就介紹一种木材消耗量極低的分層崩落法的佈置方案。一、操作情况矿塊是一扁豆狀的品位较高的高硫矿床,为急傾斜,矿体厚度6～10公尺不等,長为20公尺,属第
Hierarchical caving mining is a relatively new mining law and a widely applicable mining law. It has a particularly favorable applicability to nonferrous metal deposits of higher value and complex shape. Therefore, its proportion in China’s non-ferrous metals mining system is constantly increasing. Especially in the current situation of particularly tight timber supply, the mines that adopt the subsidence method and how to solve the problem of large amount of wood consumption which are incessantly collapsing have become urgent problems to be solved. This article describes a very low consumption of timber arrangement of the caving method. First, the operation of the nuggets is a lentil-shaped high-grade sulfur deposits, for the sharp tilt, ore thickness of 6 to 10 meters, 20 meters long, is
