随着现代科学技术的发展,国外一些露天矿山已拥有大型高效的采剥设备,以及灵活性较强的大吨位汽车,使矿山的采剥能力获得很大提高;与此同时,也带动和促进了采剥工艺的革新.例如国外以组合台阶、陡工作帮坡角和分期开采为特点的采剥方法(以下简称陡帮法),就是在这样的物质条件下,为追求高额利润而产生并不断完善起来的.它的最大优点是能推迟剥离和均衡生产剥采比,从而可使企业获得更大的经济效益.
With the development of modern science and technology, some open-pit mines in foreign countries already have large-scale and efficient mining and stripping equipment, as well as large-tonnage vehicles with high flexibility, which greatly improve the mining and stripping ability of mines. At the same time, they also promote and promote For example, the foreign stripping method characterized by combination of steps and steep work for slope angle and staged mining (hereinafter referred to as the Steep Method) is the result of the pursuit of high profits under such material conditions And continue to improve it.The biggest advantage is its ability to postpone the stripping and balance the production of stripping ratio, enabling businesses to obtain greater economic benefits.
