ShortTerm Planning for Open Pit Mines: A Review

from the top down Openpit mining is suitable for orebodies located close to the surface, with underground mining techniques typically applied where this is not the case Metal ores including iron, copper, and gold, and other materials such as coal, diamonds, limestone, and uranium, are commonly extracted using the openpitminingmethod ALimestone deposits exist in every state in the U S but only a small portion is of sufficient purity for industrial use The lower grades are generally suitable for agricultural purposes Better than 90% of the limestone quarried is from openpit operations with the remainder from underground mines Lime manufacturing plants vary in:The Lime Industry’s Problem of Airborne Dust

1131 Openpit mining Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore In many cases, logging of trees and clearcutting or burning of vegetation above the ore deposit may precede removal of the overburden TheOPTIMIZED OPEN PIT MINE DESIGN, PUSHBACKS AND THE GAP PROBLEM—A REVIEW 511 JOURNAL OF MINING SCIENCE Vol 50 No 3 2014 Fig 3 Graph G with dummy node x0 and arcs added from the dummy node x0 to all other nodes It is clear from the definition of our graph G that a graph closure in G represents a physically feasible pit, if not, then a block not in our closureOptimized open pit mine design, pushbacks and the gap

(PDF) Surface Mine Design

An open pit mine is an excavation or cuts mad e at the surface of t he ground to extract ore which is open to the sur face fo r the mine’s operational time In order to exposeareas In open pit mining, thick seams (tens of meters) are mined by traditional quarrying techniques Underground mining is used for deep seams Underground mining methods vary according to the site conditions, but all involve the removal of seams followed by more or less controlled subsidence of the overlying strataCoal Mining and Production MIGA
