Highwall mining is an efficient, proven and durable method for mining coal from exposed horizontal seams — producing an average of 110 000 tonnes (120,000 tons) of coal per month in coal seams up to 300 m (1,000 ft) in seams dipping up to 8 degrees — recovering up to 70 percent of in-place coal. The entire mining cycle is completed by ab) In room and pillar mining, the recovery rate is about 40–60%. Whereas in long wall mining method, the recovery rate is as high as up to 75%. c) In thick coal seams, long wall mining method is used, whereas in thin coal seam, room and pillar method is used. It has thickness ranging from 0.75 to 4.0 m.Coal mining trends, approaches, and safety hazards: a brief

Highwall Mining in India Springer
There are two variants of highwall mining systems- auger mining and continuous highwall mining. Auger mining has been used for contour mining since 1940. In auger mining, a circular cutter head much like a drill bit cuts the coal and the coal is scrolled to the surface by a series of open spiral flights driven from the launch vehicle.Compared with sequential mining, the skip mining method achieves higher speed of highwall stabilization and smaller plastic zone of coal pillar with its maximum strength decreasing by 12%.(PDF) Ground control for highwall mining ResearchGate

Surface and Highwall Mining Equipment Mining Technology
Highwall mining is a hybrid form of mining that accesses coal reserves from the base of an exposed highwall. It is typically used when the surface mining operation reaches the economic limitation imposed by the stripping ratio. Highwall mining can extract the remaining ore at low capital cost than underground mining and uses different equipmentThe following are the SFs and design criteria typically used in designing a highwall mining excavation area: A highwall mining panel should not exceed 20 openings between barrier pillars. Web pillar SF ≥ 1.6 for normal operations. Web pillar SF ≥ 2.0 for protection of critical structures. Minimum 0.8 web pillar width-to-height (w:h) ratioHighwall mining of thick, steeply dipping coal–a case study

Reasonable coal pillar design and remote control mining
Zonal mining is commonly used in regions where only minor ground placement is permissible. With this method, the main haulage and ventilation roadways are designed and excavated from the exposed position of the coal seam in the end-walls. For the irregular and small area of an end-wall residual resource, the costs remain high [12–14].while auger system excavates single or double holes typically from 1.5 m to 1.8 m in diameter [2]. The penetration depths range from 50 m to 500 m depending on the highwall mining systems andInternational Journal of Mining Science and Technology

Rai, "Some considerations of highwall mining systems in coal mines", 17th International Mining Congress and Exhibition of Turkey, IMCET2001, The major candidates of MPT in underground coal mining are longwall, high wall, and continuous miner. However, these methods are mostly applicable to medium-thick (2 m–6 m) coal seams. The Indian coal deposits are of varied nature like thick, thin, inclined, etc. Especially, there is no option other than longwall technology to extract coalMass Production Technologies for Underground Coal Mining

Application of short-wall continuous mining and continuous
The development and utilization of coal resources have caused serious surface collapse and destruction and ecological, environmental pollution. As the main method of green mining, backfill mining fills gangue and other wastes into the goaf to control the surface subsidence and processing coal gangue, which has broad application per system. Highwall mining also has a significant operating cost advantage over underground mining, because it is less labour intensive. The current highwall mining systems originated in the USA in the mid-1970’s. They have been used for commercial mining since the early 1980’s in the USA. These technologies were first introduced intoHighwall Mining Stability Atlantis Press

As a consequence of open cut mine application, a great deal of coal is left out in the highwalls of the mined-out pits. Highwall mining systems can be used to recover this coal. The use of highwall mining systems has increasingly come into play in the US and Australia. Application of highwall mining system in weak geological condition
