Dangping Tungsten has been using traditional mining technology for many years. In practice, the problems of low production capacity, low labor efficiency, poor safety conditions and high labor intensity are increasingly prominent. In order to find a safe and efficient mining method suitable for the steep and medium-thick ore body of the mine, the medium-diameter deep-hole mining technology is proposed on the basis of the large-diameter deep-hole mining technology, and representative ore blocks under complex conditions are selected to carry out on-site industrial tests. The test results show that the medium-diameter deep-hole staged open stoping method is an advanced and reasonable mining method. Compared with the staged open stoping method, the ore block production capacity has doubled, the mining cost has decreased by 15.47%, the explosive unit consumption has decreased by 11.76%, and the loss rate and dilution rate indicators have been greatly optimized, creating good economic and social benefits, which is of great significance for the promotion of small and medium-sized mines.
