“松土机—铲运机”用于露天开采是最近十几年国外一些国家在表土和软岩开采中发展起来的一种新工艺。它利用松土机破碎岩层,然后,铲运机自行装载、运输、卸载。整个工艺简单,机动灵活,一机多能,劳动生产率高,将为提高经济效益创造条件目前,我国露天开采铁矿石占90％,有色金属矿占50％,建筑材料为100％,煤矿占5％。 “Ripper - Scraper” for open pit mining is a new technology developed by some foreign countries in the past ten years in topsoil and soft rock mining. It uses a ripper to break the rock, and then the scraper loaders, transport, unload. The whole process is simple, flexible and flexible, a machine capable of high labor productivity, will create conditions for improving economic efficiency At present, China’s open-cast iron ore accounted for 90% of non-ferrous metal deposits accounted for 50% of the construction materials for 100% of coal 5%.
