    2 The elevation of wellheads such as shafts, inclined shafts, flat rafts, and slopes should be higher than the highest flood level in the local history by more than 1 m ;
    3 Each mine shall have at least two independent safety exits to the ground. The distance between the safety exits shall not be less than 30m . For large mines, the geological conditions of the deposits are complex, and when the length of the strike exceeds 1000m , safety shall be added at the end of the ore body. Export;
    4 The inlet air well should be located on the upwind side of the local dominant wind direction. The air entering the mine should not be polluted by harmful substances. The return air well should be located on the downwind side of the local dominant wind direction. The discharged sewage should not cause the mining environment. Hazard; the distance between the output shaft of the radioactive mine and the inlet well should be greater than 300m ;
    5 Wellhead industrial site should have stable engineering geological conditions, should avoid legally protected cultural relics, scenic spots, inland low-lying areas and goafs, and should not be harmed by ground rolling stones, landslides, flash floods and avalanches, Wellhead Industry The elevation of the site should be higher than the highest flood level in the local history;
    6 Wellhead industrial site layout should be reasonable and compact, save land, do not occupy or occupy less farmland and cultivated land, and should leave room for development for enterprises that may expand production scale;
    7 Mines located in areas with seismic intensity of 6 degrees or above, the main exits of the main wellbore and the main structures and structures in the industrial site shall be designed for seismic design.
What are the requirements for the development of roadway location and industrial site layout for metal deposits?
    1 Shaft, inclined well, and flat shovel should be selected in areas with concentrated resource reserves, small ore transport, and stable rock formations. Avoid aquifers, faults, karst development strata or sand layers, and arrange geological inspection. The engineering geological examination holes of the hole, inclined well and flat raft shall be arranged in the longitudinal direction;
