This paper explains how a large Underground Crushing Chamber of 140m 2 of section and 35m length has been preliminary designed and optimized by applying a combination of two geotechnical well-kwon software A 3-dimensional boundary element stress analysis as EXAMINE 3D and finite element modeling program as PHASES 2D.
Preliminary design of underground crushing chamber ... Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies.
Our design entailed an underground crushing chamber with dual ore passes and an associated material handling system. At the top, heavy duty grizzlies and rock breaker arrangements accept the run-of-mine ore from production operations, while discharge chutes at the bottomcomplete with Ross Feederssupply the main vibrating grizzly feeder.
underground crushing system design Chuquicamata underground mine design the simplification of the ore handling system of Lift 1. The ore handling system layout plays a fundamental role in cave mining projects, not only because it is one of the main drivers in the production capacity and reliability of the mining system, but also because it is a fundamental variable in the footprints ...
Typically in underground operations the crusher feed is not coarse and lumpy as in an open pit and is usually passed over a grizzly before crushing. It would take some special circumstances to justify the additional excavation required, additional equipment cost and more difficult maintenance.
Feb 26, 2014 PRIMARY CRUSHER SELECTION CRITERIA Will it produce the desired product size at required capacity Will it accept the largest feed size expected What is the capacity to handle peak loads Will it choke or plug Is the crusher suited to the type of crushing plant design Is the crusher suited for underground or in-pit duty ...
