加强技术改造 促进矿山发展

Strengthening technical transformation to promote the development of the mine

二矿区是金川有色金属公司主要矿山，一期投产后按原来３０００ｔ／ｄ设计能力，服务年限为１０年左右。矿山二期工程虽在建设中，但工期拖后，一、二期工程衔接不上，如不采取措施，矿山产量将要大幅度下降，为此公司对二矿区投入适当资金，加强技术改造，并在技改中引进多项新技术、新工艺。技改后，矿山实际生产能力比原设计提高了４０％左右，从而使公司经济效益、电镍产量也逐年上升。

NO. 2 mine area is the main mine of Jinchuan Non - ferrous Metals Complex. Accord- ing to the design duty (3000t/d), the service life of the first phase of the project is about 10 years.Though the second phase of the project is building, it is delayed by some reasons. The productioncan' t be continued from the first to the second phase. If any measures hadn't been adopted, theproduction of the mine would have been reduced largely. So Jinchuan Non-ferrous Metals Complex have increased the investment to NO. 2 mine area and lots of new quoted technology andcrafts are adopted in technical transformation. After the technical transformation, the actual production capacity of the mine has increased 40%, and the economic benefit and the production ofelectrolytic nikels are rising year by year.
