Putting the coarse crushing in the underground to avoid the ground dust and noise pollution; filling the goaf with waste residue and tailings to minimize environmental disturbance caused by waste residue and tailings; the heating equipment adopts energy-saving electric boiler to eliminate the influence of flue gas on environment; two sets of buried water systems are built, which directly recycles industrial water with a utilization rate of 95%, the fresh water s’ consumption is controlled within 0.2 cubic meters per ton of ore, the treated domestic wastewater has been used for greening to realize zero discharge of wastewater.
| 
 The functional layout of the mine is scientific and reasonable, the stepped layout of plants realize the self-flow transportation of pulp. | 
 After the treatment of flotation wastewater and domestic wastewater reaches the standard, it’s used for secondary production and green irrigation and clean. | |
| 
 The treated domestic wastewater is used for environmental greening and the industrial water is directly recycled to achieve zero discharge. | 
 The tailings dump project has won the national invention patent as well as the national utility model patent. |
