近十多年来,世界各国露天采矿正在向大型化发展。据有关资料介绍,国外大型深凹露天矿如果边坡角增加1°,就可以节省1500～2000万美元的投资,我国德兴铜矿的边坡角增加1°可以减少岩石剥离量1000多万米~3,这是一个相当可观的数字。但是,由于边坡角确定不够合理而造成边坡滑坡,也会给生产带来很大的损失。所以,对露天矿边坡稳定性分析及其边坡的研究具有十分重大的经济意义。
In the past decade or so, open-pit mining in various countries in the world is now undergoing large-scale development. According to the relevant information, a large open pit in foreign countries can save 15-20 million USD if the slope angle is increased by 1 °. Increasing the slope angle of Dexing Copper Mine by 1 ° can reduce the amount of rock stripping by more than 10 million M ~ 3, this is a very impressive figure. However, due to the slope angle is not reasonable enough to cause landslides, it will also bring great losses to production. Therefore, it is of great economic significance to analyze the stability of open pit slope and its slope.
