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. Soft rock mining refers to excavation of softer minerals such as salt, coal ...
Underground Mining. Underground modes of access include drift, slope, and shaft mining, and actual mining methods include longwall and room and pillar mining. Drift mines enter horizontally into the side of a hill and mine the coal within the hill. Slope mines usually begin in a valley bottom, and a tunnel slopes down to the coal to be mined.

Surveying in the mining industry, both in open-pit and underground mines, often goes hand in hand with terrestrial laser scanning (TLS), which is deployed to verify the spatial changes of mining works. Thanks to its high point density and high accuracy, TLS is a very suitable surveying technique for monitoring movements and deformations.
Sep 29, 2000· This article will discuss the similarities and differences between surveying in the sunlight and surveying deep underground. In Alabama, where my coal mining experience has been, the seams are fairly level and range in thickness from around 2' to as much as 15'.
Drainage Methods. Gas drainage for the purpose of eliminating the outburst hazard consists of drilling holes within the seam being mined to allow gas to bleed off from the coal into the hole. In its state, the gas is "adsorbed" onto the coal, a physical bonding largely governed
