Sub Level Caving - PHDessay

Description of sublevel caving method – 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.

In sublevel caving operations, it is imperative that the production blastholes be drilled accurately so that there is no risk of unblasted ore remaining between adjacent drawpoints. Post-drilling assessment is the process of mitigating this risk by verifying that blastholes have been drilled accurately with the correct length and orientation, following the blast design.

Mining by Sublevel Caving. In sublevel caving, relatively thin blocks of ore are caused to cave by successively undermining small panels. The ore body is developed by a series of sublevels usually spaced at vertical intervals of 18 to 25 or 30 feet (more recently, intervals of 50 feet or more have been. used).
