3 Major Types Of Coal Extraction
Coal mining - Wikipedia
Coal extraction methods vary depending on whether the mine is an underground mine or a surface (also called open cast) mine. Additionally, coal seam thickness and geology are factors in the selection of a mining method. The most economical method of coal extraction for surface mines is the electric shovel or drag line. The most economical form of underground mining is the lo
