Mining Methods Environment Guide

Mining Methods. There are four key stages of work involved in mining for minerals. These include: 3415, 3416 Prospecting The purpose of this stage is to identify areas that are likely to contain mineral deposits. The work includes geological, geochemical and geophysical surveys (e.g. seismic surveying), aerial surveys, including the taking of samples by low-impact mechanical methods.

The two main types of mining are surface mining and underground mining. Mining is further divided into several other categories including room and pillar mining, slope mining, block caving, quarrying, open-pit mining and in situ mining....

110 Different Types of Mining Operations and Mines

There are five basic types of surface mining, including open-pit mining, strip mining, dredging, mountaintop removal, and highwall mining. All of these methods remove the waste material or the overburden, that is above the desired resource. Often, surface mining is preferred over underground mining, or subsurface mining, for numerous reasons.
