Bayan Obo West Mine Combination Of Steps Of Mining Parameters Research

At the end of the1960s, the United States mining scholars put forward a newmethod of mining technology-steep slope mining, They also expounded the conceptof the steep slope mining, and improved the inclination angle of work, to reduce thestripping of the mine infrastructure, and defer pre-production stripping ratio and theresulting economic benefits a lot of work. From the late1970s, Chinese expertsstarted this aspect of exploration and research work. In the late1980s, they not onlystudy of theory in this aspect, and began a practice to try. In recent years, theoreticalresearch and practical experience in combination bench exploitation in China hasmade significant progress, but also the car transport large open-air iron ore still lack ofpractical experience. Its mining of parameters, in particular, is a combination of stepprocess with different mining parameters with the internal laws of the equipmentefficiency, operating cost, but also the lack of scientific method of analysis, it isdifficult to give a good answer. While it is recognized that the combination of steps ofmining postpone the amount of stripping rock of the enormous economic benefits, butlimits the deeper understanding of mining right combination of steps, affecting thepromotion and application of the combination bench exploitation. It can be seen tocarry out the combination of steps of mining parameters of the study has importanttheoretical significance and of great economic significance.This topic for a specific project examples, Baotou Steel Group Bayan Obo WestMine technology with ways to combine and analyze the mining industry practicalexperience and practical mining experience, the different mining parameters, differentmining parameters with the equipment efficiency, operating costs the inherent laws ofthe search for technically feasible, economically optimum mining parameters. Providea reliable process and technical parameters as well as the combination of stepsexploitation of new technology in China after the new construction and renovationand expansion of large-scale automobile transportation open pit, ore raw materials forBaotou Steel Group, and also for the Bayan Obo West Mine to achieve greatereconomic benefits to make a contribution.
