Aug 31, 2014· Recently, this technique has become popular in underground mining operations in Western Australia and with this growing popularity it is important that surveying professionals have an indepth understanding of methodology, accuracy and limitations of the technique.
Surveying in the mining industry, both in openpit 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.

Underground Coal Mining Methods and Engineering Dust Controls. An underground mine consists of the portals (entrance and exits to the mines), mains, submains, panels, and working faces. The panels are the working sections of the production operation. Depending on the mining method, a working section can have one or more working faces.

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''.
Underground surveying is quite different from surveying on the surface. In tunnelling or mining operations it may be hot, wet, dark, cramped, dusty, dirty and dangerous, and usually most of these. The essential problem in underground surveying is that of orientating the underground surveys to the ...
Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on .
