underground coal mining technology
Coal Mining Market: Allied Market Research
On the basis of mining technology, the market is bifurcated into surface mining and underground mining. Surface mining is further segmented into strip mining, auger mining, openpit mining, and mountain removal mining.
Underground mining of thick coal seams ScienceDirect
But underground mining of a thick coal seam inherits a number of geotechnical challenges which makes it difficult for mining and mechanization. Multislice working of a thick coal seam is a normal choice to reduce operational constraints and optimize recovery and safety during underground mining.

How Underground Mining Works | HowStuffWorks
Technology applications and basic decisions about design and mining method rest on considerations like the type of ore being mined, composition of surrounding rock, shape and orientation of the ore deposit, geologic features underground, and simple economics [source: United Mine .
COAL Earth Sci
Continuous mining is the most prevalent form of underground mining, accounting for 56% of total underground production. In continuous mining, a machine known as a continuous miner cuts the coal from the mining face, obviating the need for drilling and blasting.
Mining terms explained: A to Z – Anglo American
Longwall mining – a form of underground coal mining where a long wall of coal is mined in a single slice. Metallurgy – the art of working metals, especially extracting them from their ores. Mine value chain – the entire mining process, from the moment the potential of an area is identified to the day product is delivered to customers.
A fuzzy method for selecting underground coal mining ...
One of the crucial decisions affecting productivity of the mine is the mining method selection. Longwall mining is quite common in underground coal mining, and it allows the use of mechanization. As application of mechanization increases, production also increases and the number of workers decreases ...
