HOW IS COAL MINED? OPENCAST MINING Opencast mining = mining that takes place from surface quarries (or open pits) All of the overlying rock (overburden) must be removed, this will be critical to the economics of the process.The sides of an open pit are dug at an angle and stepped in order to increase stability and prevent collapse. The flat parts of the steps are called benches.

Oct 01, 2017· Unfortunately, fewer works on the use of digital photogrammetry for study on slope stability that is influenced by open-pit to underground mining transition. The possibility of use of digital photogrammetry for the mining engineering could be significant as apart from accuracy and resolution. It is non destructive and low cost.

Coal and the environment

With the exploitation of underground sources, nature receives a huge negative impact on the local environment introducing surface subsidence. A mining region needs to be observed in sequences before, during, and after coal extraction from the coal mine. Different measuring methods exist to monitor subsidence, and all of them apply various instrumentation.

how to use photogrammetry in coal mining

Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many U.S. coal beds are very near the ground's surface, and about two-thirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves.
