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.

METHODS IN MINING BY SUBLEVEL CAVING

A method of mining by sublevel caving comprising the steps of forming at least two vertically directed ventilation shafts disposed in spaced relation to one another within a rockwall adjacent an orebody, driving a plurality of horizontally directed cross cuts extending in vertically spaced relation to one another from said rockwall and from said ventilation shafts into said orebody, .

Caving methods. Caving methods include block caving, sublevel caving, and longwall emphasis, allow me to repeat what I said earlier: caving methods are used in settings where the ore or the host rock is so weak that it cannot support its own weight for any period of time; the methods only work if the rock or the ore will readily cave under its own weight.

Sublevel open stoping

This method is usually considered as an alternate to sublevel caving when a lower dilution method is needed and where the rock is fairly competent. The production for a mine using sublevel stoping can range from 15 40 tons/employeeshift, while one stope can produce greater than 25000 tons per month.

LKAB develops a new mining method

The method currently applied in LKAB's underground mines, largescale sublevel caving, has been very successful. This is an effective method that enables mining of large volumes at a relatively low cost. However, there is some question as to how appropriate this method is for mining at ever greater depth. "There are some mines with production ...
