欧美国家对露天矿一般实行陡帮开采。利润在那些国家支配一切,无利可图的技术不可能被那里广泛采用。在我国曾有不少文章指出陡帮开采有推迟剥离高峰和节约基建投资的作用,但这些作用对全矿开采经济效果的影响还有待研究。技术是科学和经济的结合,欧美国家同我国的经济结构和经济体制不同,技术发展和经济繁荣程度不同,在国外能够实现和发挥经济效果的陡帮开采技术,在我国是否也能够如此?这不仅涉及到它对我国的利弊得失问
Europe and the United States generally open steep mining to open-pit mines. Profits in those countries dominate everything, unprofitable technology can not be widely adopted there. There are many articles in our country that pointed out that the steep-gang mining has the effect of postponing the peak of stripping and saving capital investment. However, the effect of these effects on the economic effect of the whole mine has yet to be studied. Technology is the combination of science and economy. How can the European and American countries, different from China's economic structure and economic system, have different degrees of technological development and economic prosperity and can achieve and exert economic effects abroad? Can this be the case in our country? Not only is it related to the pros and cons of it to our country
