前言印度的地质矿床条件变化很大。有些矿山随着深度的增加,将出现不利的水文地质问题。现将若干矿山未来开采的深度介绍如下: 有些矿山是根据经验设计的,深度很浅时就发生大块边坡的破坏,有些矿山存在剥采比高达1:5～1:7的问题。运输道路要按重型胶轮载重车辆设计,建议采用50t至85t自卸汽车。水压增大的问题很突出,垂直泵水和水平排水显得很重要。 Preface India’s geological deposit conditions vary widely. With some mines increasing in depth, there will be adverse hydrogeological problems. The depth of future mining of several mines is described below. Some mines are designed on the basis of experience. At a very shallow depth, massive slope failure occurs. In some mines, the problem of stripping ratio up to 1: 5-1: 7 is present. Transport road according to heavy rubber tire truck design, it is recommended to use 50t to 85t dump truck. The problem of increasing water pressure is very prominent, vertical pump water and horizontal drainage is very important.
