金屬礦深部開采現狀與發展戰略

Current status and development strategy of metal mines

  • 摘要: 在調研國內外眾多金屬礦山和收集大量相關文獻的基礎上, 綜述了國內外金屬礦山開采現狀及研究進展, 聚焦深部開采主要工程技術難題, 從開采動力災害預測防控、深井高溫熱害控制治理、深井提升、深井開采方法工藝變革、深部選礦新技術、智能無人采礦這六個方面, 提出了解決我國深部開采難題的戰略建議, 結果表明: (1)5000m開采深度將會是我國金屬礦深部開采中長期戰略研究目標; (2) 無繩垂直提升技術具有提升效率高, 使用限制少的特點, 建議我國重點針對此類技術裝備研發; (3)將深部礦產資源開采與深部能源開發相結合, 可以有效降低深部降溫成本, 是解決深部采礦經濟性的新途徑; (4) 新一代采礦技術需對原有的采礦模式和開采工藝進行變革, 機械連續切割破巖技術是未來超深礦井建設的重要發展方向; (5) 充填法是保證深部開采安全最有效的方法之一,應對充填材料、充填工藝進行更深入的研究; (6) 我國尚不具備全面推廣遙控智能化無人采礦的條件, 可以通過產學研聯合攻關等方式逐步提高礦山生產自動化和遙控智能作業水平.

     

    Abstract: Mineral resources provide an importantmaterial basis for a country's economic and social development.After decades of large-scalemining, the shallow-metalmineral resources of China have been reduced annually and the development ofmetal resources has reached the stage of comprehensive promotion of deepmining at present.Based on the investigation of a number ofmines in China and abroad and an extensive review of the relevant literature, this study summarizes the present situation and research progress ofmetalmining by focusing on themain technical engineering problems of deepmining and proposing some strategic recommendations to solve the problems of deepmining from six aspects, including the prediction and prevention of dynamicmining disasters, the control of hightemperature thermal environments and treatment of hazards, deep-well hoisting, deep-wellminingmethod and technology reform, new technology for deepmineral processing, and intelligent unmannedmining.The results include the following: (1) Themedium and long-term strategic research target for the deepmining ofmetals in China will be the depth of 5000m.(2) High efficiency and less restriction are characteristics of the cordless vertical lifting technology, which suggests that China should focus on the research and development of this technology and related equipment.(3) Combining themining of deepmineral resources with that of deep energy resources can effectively reduce the cost of deep cooling and offers a new way to solve the economic challenges of deepmining.(4) Newgenerationmining technologies need to change the original mining models and technologies, and the continuous mechanical cutting and rock breaking technology represent an important development direction for the future construction of ultra-deepmines.(5) The fillingmethod is one of themost effectivemethods for ensuring deep-production safety, and further research is needed on the fillingmaterial and filling process.(6) The conditions necessary for comprehensively promoting remote intelligent unmannedmining in China do notyet exist, andmining progress can be facilitated by university-industry collaboration.
