The overall coal mining process consists of several sequential stages: (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of a mining plan; (3) securing the markets; (4) developing the mine; (5) extracting the coal; (6) processing the coal if necessary; and (7) .
If you want to mine coal for steam power/smelting early on before electrical drills, then yes I'd say this is a good setup, assuming you then feed the belt to the power/smelting stations, instead of piling them in a chest. I always use this setup early game, and for quite a while into...

Coal is a resource found in the world. It can power Coal Generators and vehicles . It burns for seconds and has a fuel value of 270MJ. Coal is mainly used for steel productions, along with many other mid .
Feb 08, 2018· Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity.
In roomandpillar mining, coal deposits are mined by cutting a network of 'rooms' into the coal seam and leaving behind 'pillars' of coal to support the roof of the mine. These pillars can be up to 40% of the total coal in the seam although this coal can sometimes be recovered at a later stage.
Surface coal mining in the steep terrain of the central Appalachian coalfields includes: mountaintop removal, contour, area, highwall, and; auger mining. Operations are concentrated in: eastern Kentucky, southern West Virginia, western Virginia, eastern Ohio, and; scattered areas of eastern Tennessee. Surface coal mining involves:
The Coal Mine Roof Rating is a roof classification system that was first introduced to the mining community in 1994. It filled a longstanding need to quantify geologic description of coal measure rocks into an engineering value which could be used for mining design purposes.
COAL MINING AND MIGRANT WORKERS. Coal mining companies had always been confronted with the difficulties of recruiting and keeping workers. This problem became severe after World War I, when miners and other young workers deserted the collieries for healthier and betterpaid occupations.
The history of coal mining goes back thousands of years. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today.
