山坡露天矿的开采常伴以多种边帮变形,其原因是山坡露天矿工程地质复杂,围岩为遭受不同程度的热液交代变质侵入岩和喷发岩,岩石强烈裂隙化。边帮变形之所以会引发大量岩石移动,是由于近边帮岩体没有或有很小的侧向支持力。文章强调指出,山坡露天矿的设计应当根据近边帮岩体的详尽工程地质资料进行,同时,必须规定对洪水和暴雨径流的防治。
The development of hillside open-pit mines is often accompanied by a variety of side-bar deformations. The reason is that the hillside open-pit mines are complex in geology. The surrounding rocks are subjected to metamorphic intrusive rocks and eruption rocks with varying degrees of hydrothermal fluids, and the rocks are strongly fissured. The reason why the deformation of the side boulder causes a large amount of rock to move is that there is no or little lateral supporting force for the rock mass near the side. The article emphasizes that the design of the hillside open-pit mine should be based on the detailed engineering geological data of the rock mass near the edge, and at the same time, the prevention and control of flood and storm runoff must be provided.
