塔尔纳赫矿区铜镍矿床的特点是存在不连续的块状结构,矿体已延深到1600米。从构造地质方面应看作是在不同方向上与矿体相交、断距从几米到几十米,为众多无秩序的破坏带所分割的地质构造。这种矿床开采时的最大难点是如何选择采矿方法和地压控制方法。设计所规定的采矿方法往往避免不了矿山压力的显现,因而必定会增加劳力和材料消耗,降低作业安全性。
The copper-nickel deposit in the Tarnach mine is characterized by a discontinuous massive structure that has been extended to 1,600 meters. From the geological aspects of tectonics, it should be regarded as the geological structure that is intersected with ore bodies in different directions and from a few meters to tens of meters away from each other for many disorderly disrupted belts. The biggest challenge when mining this deposit is how to choose the mining method and ground pressure control methods. Mining methods specified in the design often can not avoid the pressure of mining, which will certainly increase the labor and material consumption, reduce job safety.
