One of the engineering disciplines requiring a unique approach for block and sublevel cave mining is ventilation. Ventilation designs must ensure production ramp-up is met during the construction phase and that steady-state operations can achieve unconstrained production.4.1 1.Production Shaft 4.2 2.

OZ Minerals is an Australian based modern mining company with a focus on copper. Their Carrapateena Project, located in South Australia is one of Australias largest undeveloped copper deposits. Construction of Carrapateena is underway and commissioning is scheduled for Q4 2019 after which the project will ramp up to steady state production. The project will be an underground sub-level caving ...The choice of an appropriate mining method is based on numerous factors such as ore strength, depth, shape, and size, among other characteristics unique to each deposit (Nieto 2011).This study focuses on two bulk mining methods, sublevel stoping and sublevel caving, which have limited selectivity and are therefore associated with higher production rates and lower unit operating costs than ...Underground production scheduling with ventilation and refrigeration ...Sublevel caving method with sill pillar is the mining process in which a level is divided into several sublevels, a bottom structure specifically used for ore removal is furnished at the lower part of each sublevel, and stoping of ore proceeds from the top sublevel to the bottom sublevel (Fig. 1).It is also called sublevel caving method with bottom structure.Sublevel Caving Method with Sill Pillar | SpringerLinkاحصل على السعر
The stopping drifts of upper and lower sublevels shall be arranged strictly in a rhombic-shaped layout so that the ore remaining at the ridges on both sides of the stopping drift of the upper sublevel can be maximally recovered during ore removal in the lower sublevel. The stoping drifts at one sublevel shall be mutually parallel.احصل على السعر
