Coal mining - Transportation, Safety, Environment: There are several methods for moving prepared coal from the mine to the markets. The cost of transport can be substantial and can account for a large fraction of the total cost to the consumer. Rail transportation is by far the most common mode of hauling coal over long distances.Before implementing a continuous mining system, mining companies must divide each mine into 20 to 30 coal beds. Then, workers must install support systems to prevent the mine from collapsing. After carving work areas into the coal beds, mining teams can begin setting up continuous miners to extract coal.

Coal ore is a mineral block that drops coal when mined. Deepslate coal ore is a variant of coal ore that rarely generates at the top of the deepslate layer. Coal ore can generate in the Overworld in the form of ore blobs. It generates in two batches per chunk. The first batch attempts to generate 30 times per chunk in blobs of 0-37, evenly from levels 136 to 320. …Once this has been confirmed, mining operations begin.
