Many underground mining methods rely on blasted rock moving under gravity to report to extraction points. Mining of orebodies dipping between 20 - 45 degrees poses a unique challenge for mining engineers in that a dip angle in this range will not allow the movement of broken ore down the footwall to the mucking horizon utilising gravity. This is more so …
Coal mining - Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata.

Underground metalliferous mines extract valuable ores like gold, silver, and copper. These operations rely on advanced underground mine ventilation and electrical systems to maintain air quality, as well as effective water management solutions to ensure safety and enhance productivity while meeting stringent regulatory standards.
In deep underground mines, mining-induced seismicity potentially creates instabilities like rockbursts and fallouts. The magnitude of the seismic event depends on energy stored in the rock mass which varies between 10 5 to 10 9 j. For mines where this is an issue, a type of rock support system that can absorb the majority of released seismic ...
Underground mining is the process of extracting minerals and resources from beneath the Earth's surface through a network of tunnels and shafts.
