In underground mining, many miners are injured or lose their lives because of roof/pillar instability each year, and this is a persistent safety risk. Characterization of overlying strata is important for the design of safe and cost-effective ground support systems. Entry roof characterization can be performed by geological back-mapping of …

In surface mining, the ore is accessed directly from the Earth's surface, and contact is maintained with the surface throughout the operation. Underground or subsurface mining is accomplished with the help of tunnels going into the Earth, and does not occur on the surface. Working Principle. In surface mining, the topsoil and bedrock is ...

Underground surveying is a type of surveying that is used to measure and map the features of the earth that are below the surface. This type of surveying is used to map the location and depth of objects such as pipes, cables, and tunnels. It can also be used to locate subsidence, or the movement of the earth's surface.

Survey pegs are plentiful underground and within direct line of sight of each other. Not all points in a mine are in direct line of sight of a survey peg, but are within direct line of sight of a point that can itself see two or more pegs. This is better for underground workings than a GPS which has to be placed at the point being measured.
