露天转地下开采的矿山边坡问题

在露天转入地下开采的矿山中,边坡岩体仍是个重要问题,本文列举一些实例说明不注意此问题而带来的危害。并在简要介绍白银折腰山铜矿露天转地下开采边坡稳定性研究的基础上,分析转入地下开采时影响边坡稳定性的因素;指出转入地下开采初期整体边坡大规模滑动的可能性不大,而局部小范围滑坡不会对开采构成危害。但是,应加强监测,作好突发性滑坡的预报工作。

THE SLOPE PROBLEMS IN CONVERSION OF SURFACE MINING TO UNDERGROUND OPERATION

In the conversion of surface raining to underground operation, the rock of slope is still a serious problem, und will cause harm if neglected, as demonstrated by some instances given in this paper. Based on the study on the slope stability in the conversion of surface mining to underground, operation, in Zheyaoshan copper mine operated by Baiying Co., the analysis of the factors affecting slope stability is made. And it is pointed out that the large scale slipping of the complete slope is too impossible in the initial stage of the underground operation, while the limited local slipping does no harm to mining operation. However, the emphasis should be placed on monitoring and measuring, and the prevention and prediction of sudden slipping should be done well.
