Sublevel Caving Technique Mining Drilling Rig

Sublevel Caving Technique - Free download as PDF File (.pdf) or read online for free. An underground mining method used in large, steeply dipping orebodies where the wall rock is of an incompetent nature. Parallel drives are developed in the ore on equally spaced levels. The ore is then drilled and blasted using longholes between levels, often in a circular or fan pattern, on retreat.
