1 Hydrogeological conditions and ore body shape are more complicated; 2 The ore body is buried deep and the ground pressure is relatively large; 3 The ore or surrounding rock is at risk of spontaneous combustion; 4 Surface or surrounding rock is not allowed to have large area subsidence or violent movement and requires special protection; 5 Mining at the same time in the open and underground. If special support methods or down-stratified filling methods can be used, it can also be used to open ore bodies that are unstable to the ore. Because the steeply inclined ore body facilitates the feeding of the filling to the stope, and can reduce the space of filling and the area of ​​the filling top. However, if it can be filled with hydraulic or wind power, it can also be used for the mining of gently inclined thin veins.

(2) Mineral deposits with conditional parts and mining technical conditions, such as:
(3) Suitable for deposits with stable ore and unstable surrounding rock
(4) Applicable to mining steeply inclined ore bodies
Applicable conditions for filling mining law
Higher (a) quality grade ore mining, and requires a relatively high recovery rate and a relatively low dilution ratio; or dilute extraction of precious metals.
