    Safety assessments of conventional coal mining under aquifers mainly use the height of the water-conducting zone (HWCZ) above the mining panel as the empirical safety criterion. However, this criterion alone fails to account for mining-induced permeability and porosity variations of key aquiclude strata (KAS) in backfill mining. Backfilling can compact and close developed fractures in …

  • Dragline Mining & Reclamation Mining

    Both mines are similar in equipment and manpower used; both produce over 2,000,000 tons of clean coal annually. Formerly, loaders and trucks, or shovels and trucks, had been used for this type of mining. The continuous acreages at Hobet's 21 mine site prompted the consideration of larger mining equipment – namely, the dragline.

  • Coal Mining | MCR Safety

    The continuous mining method, an innovation from the late 19th and 20th century, eliminates the drilling and blasting operations found in conventional mining. This method uses a machine called a continuous miner. It continually extracts the coal, while loading onto a conveyor system. Coal Production Regions.

    As the shearer traverses along the coal face the supports are advanced to enable the shearer to cut a fresh web of coal when it returns. There are two methods of advancing powered supports, these are: Conventional Method of Advancement. In the conventional method the supports are stood up to the conveyor before the shearer cuts a web of coal.
