1 前言梅山铁矿自建矿以来至今已度过30多年的生产建设生涯。采矿于1975年投产,选矿于1980年投产。1982年经国家验收,核定一期综合生产能力为150万t/a。一期原设计规模为250万t/a。后调整为200万t/a。1993年采选综合生产能力已突破200万t,达到了一期设计指标。采矿一期延深工程1993年初已竣工投入生产。二期扩建工程初步设计已通过国家审查,即将开工。二期工程峻工后,矿山的生产能力将扩大到400万t/a。梅山铁矿30多年的发展历史表明,矿山的生产和建设离不开科学技术,离不开科技
1 Preface Since its construction, Meishan Iron Mine has spent 30 years of manufacturing and construction career. Mining put into operation in 1975, beneficiation was put into operation in 1980. In 1982 by the state inspection, approved a comprehensive production capacity of 1.5 million t / a. The original design of a scale of 2.5 million t / a. After the adjustment to 2 million t / a. In 1993, the comprehensive production capacity of mining and dressing exceeded 2 million tons, reaching the first-phase design index. The first phase of the mining project has been completed and put into production in early 1993. The initial design of Phase II expansion project has passed the national review and is about to start. After the completion of the second phase of the project, the mine’s production capacity will be expanded to 4 million t / a. The history of the development of Meishan Iron Mine more than 30 years shows that the production and construction of mines can not be separated from science and technology and can not be achieved without technology
