A Dynamic Intersecting Arrangement Model Based On

the sublevel caving method is used for mining between sublevels from top to bottom. when ore is extracted, overlying waste rock fills the void created by ore extraction, so the ore is always surrounded by the overlying waste rock. the caved ore is drawn from drifts under loose cover-layer-rock, so ore loss and dilution readily occur
