无轨机械化采矿技术于20世纪70年代末引入我国矿山,经过30余年的消化吸收,已经成为一项成熟的采矿工艺技术。进入21世纪,随着我国市场经济的迅猛发展,矿山的生产效率,已经成为矿山经济发展的重大问题,这使高效率无轨采矿技术得到了普遍的运用。同时,由于资源观念的根本变化,低品位边际资 Trackless mechanized mining technology was introduced into our mines in the late 1970s. After more than 30 years of digestion and absorption, it has become a mature mining technology. In the 21st century, with the rapid development of market economy in our country, the production efficiency of mines has become a major issue in the economic development of mines, which has led to the widespread application of high-efficiency trackless mining technology. At the same time, due to the fundamental changes in the concept of resources, low-grade marginal capital
