| This paper interpreted basic theory and research orientation on deep mining of underground in domestic and overseas. After carefully analyzed and investigated Jinchuan Mines 40-years mining experiences and lessens, it carried out studies through system theory on mining methods, development system, deep ground supporting for Jinchuan No.2 Mine deep mining project which is thought as a difficult mining problem in the world. A lot of original-viewed optimized schemes are presented and safety reliability, technique feasibility and rationality for deep mining program are demonstrated in synthesis. Meanwhile the paper also provided research subjects and directions in the future and prognosticated development of deep underground mine in China.This research methods and conclusion may guide underground mines with similar conditions of Jinchuan No.2 Mine. |
