1.1 PHASES OF A MINING PROJECT ELAW

1.1.3.1 Open-pit mining Open-pit 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 clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The

An Introduction To Surface Mining

However, surface mining can be more environmentally-damaging than subsurface mining. Types of Surface Mining Open-Pit Mining. Known also as “open-cast mining”, open-pit mining is the most common type of surface mining. Open-pit mines are enormous holes in the ground; created and increased by blasting and drilling rocks apart.

Mining Surface mining Britannica

Mining Mining Surface mining: It has been estimated that more than two-thirds of the world’s yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.
