discard material. The process of mining and beneficiation, stockpiling of coal, coal products and waste is an important factor in management practice, as it makes the environment and water more vulnerable to degradation. More care should be taken in understanding and managing exposed rock or waste piles, which creates paths for pollution migration.
Mine:an excavation made in the earth to extract minerals Mining:the activity,occupation,and industry concerned with the extraction of minerals Mining engineering: the practice of applying engineering principles to the development,planning,operation,closure,and reclamation of mines Some terms distinguish various types of mined minerals.
Bulk Material Handling: Products. Belt Conveyor Conveying Belt conveyors complement machines used in bulk material handling and mining systems. They are used as the main component in bulk material transport systems. Combined Stacker / Reclaimers Bulk Material Handling Combined stacker / reclaimers can operate as stackers or as reclaimers.
Key end users such as Coal is expected to increase by 1–2 percent by CAGR by output during 2018–2022, while metal production is expected to increase by 2–3 percent during the same period; Belts and accessories used for conveyors constitutes around 23 percent of the Billion global material handling equipment market share.
Underground Mining. The length of the longwall block is about 3,000 meters to 5,000 meters. In a 3 meter thick coal seam the amount of coal in place in a block is six to seven million tons. The basic equipment is a shearer (a cutting machine) mounted on a steel conveyor that moves it along the face ( Figure 37 ).

® Plow Systems for Low Seam Coal. Plowing is the preferred longwall mining technique for seams below m (71 in), and under specific geological conditions, even below m (90 in). Today, is the market leader in the field of fully integrated and automated plow systems. Sophisticated ® automated plow systems today operate...
PDY 310. 23 Strip Mining. Strip mining is ideally applied where the surface of the ground and the ore body itself are relatively horizontal and not too deep under the surface, and a wide area is available to be mined in a series of strips. Typical examples of this type of mining are the larger tonnage coal mining operations in Mpumulanga.
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) .
