Coal Mining Structure Design

Coal Mining - an overview ScienceDirect Topics

01/04/1990  Coal mine design practice has shown that safety and productivity are mutually inclusive goals. Underground mining methods are a mix of continuous and batch processes. For example, while the continuous miner is extracting the coal from the face of the entry, the process is in continuous mode.

Coal Types, Formation and Methods of Mining - epcamr.org

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. Another type of continuous underground mining is called longwall mining.
