Get A Free Quote Sublevel stoping. Hole diameter average 51 mm, Burden and Spacing vary from 1. Based upon the damage radius Rd: Selection of the biggest equipment that the mine will permit and Scoop trams or Load Haul Dump LHD vehicles transport the muck, loosened rocks, to an ore pass where the rocks are lifted to the surface.

Waste dilution and ore losses are drawbacks for sublevel caving.

sub level caving mining method selection

The ore is crushed, loaded into skips, and sent to surface for processing Sublevel Caving Layout Extensive research has been performed on layout parameters, using model experiments and theoretical applications.

Broken ore is extracted from the drive before the next blast takes place. If it is assumed that: Hole diameter average 51 mm, Burden and Spacing vary from 1. Partha Das Sharma, B.

block caving cost model

Parallel drives are developed in the ore on equally spaced levels. When development is complete, i.

sub level retreat mining method

Partha Das Sharma, B. Longhole drilling is a procedure which is done independent of other jobs, often well ahead of charging. Partha Das Sharma, E. The ore is then drilled and blasted using longholes between levels, often in a circular or fan pattern, on retreat.

It is, however, important to acknowledge the limitations present in model testing. Legitimate interrelation has been found between model tests and actual in mine behavior.

In this method, the face is formed perpendicular to the seam strike and implemented in the form of slices 7.SUBLEVEL CAVING TECHNIQUE by Partha D Sharma - Issuu Sublevel caving techniqueSimplicity and low cost are the essence SUBLEVEL CAVING TECHNIQUE SIMPLICITY AND LOW COST ARE THE ESSENCE Author: Partha Das Sharma, mi-centre.com(Hons.) in Mining Engineering, mi-centre.com: [email protected], Blog.

SUBLEVEL CAVING TECHNIQUE SIMPLICITY AND LOW COST ARE THE ESSENCE Author: Partha Das Sharma, mi-centre.com(Hons.) Below are some salient features of Sublevel caving technique: Application * Weak walls and strong ore preferred though weak ore can be mined too.

* Steep dip: A vertical dip is best, while dip>60 is fine too. Sublevel caving techniqueSimplicity and low cost are the essence controlled drilling and blasting. Sublevel caving is in many respects simple.

It can be used in orebodies with very different properties and it is easy to mechanize.
