It adopt dryfillingmethod in the orebody above -350m level and adopt the method of sublevel caving in the orebody under the level. Exploitation engineering already reach -385m level.
The pilot study was done on the filling shape of liquid metal in lost foam process with dry sand by using rapid photography method and contact time method.
