“松土机—铲运机”露天开采新工艺在山西孝义铝矿工业试验成功,为我国开采表土、软岩创出一条新路,是开采工艺上的重大改革,填补了我国露天开采工艺的一项空白,经济效益显著,其技术经济指标接近国外先进水平。随着国外大型松土机和铲运机的出现,最近十几年在美国、法国及苏联等少数国家发展起来的这种新工艺的特点是:工艺简单,设备少,机动灵活,劳动生产率高,综合效率高,投资少,成本低,有利复土造田
The new technology of open-pit mining of “soil ripper-scraper” succeeded in Shanxi Xiaoyi aluminum mine. It has created a new road for the mining of topsoil and soft rock in our country. It is a major reform in mining technology and has filled the open-pit mining technology in China A blank, significant economic benefits, its technical and economic indicators close to foreign advanced level. With the advent of large-scale overseas ripper and scraper, the characteristics of this new process that has been developed in a few countries such as the United States, France and the Soviet Union in recent ten years are: simple process, less equipment, flexible and labor-intensive Comprehensive high efficiency, low investment, low cost, favorable soil rehabilitation
