Coal mining is only a temporary use of land, so it is vital that mine rehabilitation takes place once operations have stopped. Detailed rehabilitation or reclamation plans are designed and approved, covering the period from the start of operations until well after mining has finished.
For example, in coal and other soft rock mines, continuous miners break and load the mineral to eliminate drilling and blasting; boring machines perform the same tasks in medium-hard rock. The cycle of operations in surface and underground mining differs primarily by the scale of the equipment.
Ancillary equipment in the form of drills, graders, rubber-tyred dozers and water carts will provide the mining equipment with support as required. Coal is extracted by front-end loaders and/or excavators loading haul trucks. The current mining equipment will continue to be used.
treacherous conditions. “Coal-cutting” machines were introduced in the 1880s. By 1912, surface mining was performed by using steam shovels designed for coal mining. Safety Mining underground certainly poses some major health risks to workers, but today's workers have highly advanced equipment that protects them in dangerous scenarios.
