Coal Mining and Processing - The National Academies Press

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) decommissioning the mine and releasing the property for post-mining use.

China’s Coal Industry Must Follow the Path of Sustainable ...

Safety during coal mining poses the largest constraint to coal production expansion. Based on the above analysis, we propose that China’s maximum annual coal production capacity should be limited to 3.8 billion tonnes (equivalent to 2.7 billion tonnes of standard coal) to maintain the healthy and sustainable development of China’s coal industry.

Constraints of coal mining - Mines and Communities

Conclusion: The above point to the constraints of coal mining in Bangladesh, irrespective of the mining method adopted -- underground or open-pit. The lesson is that one cannot be too aggressive in mining coal in Bangladesh because of the difficult geological setting, environmental effects and large scale social (resettlement) problems.

In contrast, room-and-pillar mining leaves pillars of coal to support the mine roof. High-extraction pillar removal results in similar subsidence as longwall mining. In the USA, longwall mining and most groundwater case studies have been conducted since the 1970s in the Appalachian coalfield, a dissected plateau region of moderate to high relief (of order 10 2 m).

Because of the bottlenecking operations in a complex coal rail system, millions of dollars are costed by mining companies. To handle this issue, this paper investigates a real-world coal rail system and aims to optimise the coal railing operations under constraints of limited resources (e.g., limited number of locomotives and wagons).
