      Using the 3Ddeposit modeling system to guide underground prospecting according to the mineralization regularity and the complicated geological structure, and many blind and edge ore-bodies are found. The main adit + main-auxiliary shaft development method and the electronic signal control system are adopted in underground transportation to improve the transportation efficiency; implements the “four modernizations” of development, such as mining mechanization, production and management frontline, construction team   miniaturization, quality management standardization; adopts the mechanical equipments such as drilling trolley, prying trolley, driverless railcar to realize mechanization and automation of drilling ,charging, mining, transportation, filling and so on.

      The beneficiation puts the coarse crushing in the underground to avoid the surface noise 

      and dust pollution, and realizes the environmental protection, energy saving and efficient 

      utilization.
