Abstract: To promote the progress in metal mine sci-technology and the metal mine sci-technology work in the "Eleventh-Five Year Plan" period, a summary is made of the achievements made in the mining technology of metal mines in China during the "Tenth-Five Year Plan" period, and its development orientation in the "Eleventh-Five Year Plan" period is proposed. It is concluded that the successful development of steep railway hauling technique, new technique of large space concentrated pillarless mining, research on key techniques for mining deep-lying deposits, etc. have greatly propelled the advance in mining technology for metal mines. The analysis indicates that the research on the technology for the transition from open-pit mining to underground mining has lagged behind the demand of production practice, there are a large number of technical problems in deep mining that remain to be solved, the mining for complex deposits is becoming increasingly difficult, domestic mining technology and equipment are still far from those of internationally advanced level and the establishment of digital mine is still at its start stage. In view of this, the development orientation for mining research work in the Eleventh Five Year Plan period is proposed, including research of new type hauling equipment and process for deep open-pit mines, research of open-pit and underground combined mining, research of technology for mining deep-lying orebody and complex deposits, research of digital mine and research of circular economy of metal mines.
