Practice and prospects of fully mechanized mining technology for thin coal seams in China by F. Wang*†‡, S. Tu*†, and Q. Bai*† Synopsis In China, thin coal seams are rich in resources but are technically challenging. The mineable reserves in these seams account for % of the total coal resources, while the current production accounts for
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically – m (2 ft 0 in–3 ft 3 in) thick). The longwall panel (the block of coal that is being mined) is typically 3–4 km (– mi) long and 250–400 m (820–1,310 ft) wide.

international coal market Coal mining is carried by Surface or ''opencast'' mining; Underground or ''deep'' mining Around 60% of this world coal production is from underground mines while 40% from surface mines. However, the proportion of coal production from underground coal mines varies widely in various countries.
This study proposes an integrated, closedcycle miningdressinggas drainingbackfillingmining (MDGBM) technique. The proposed approach involves the mining of protective coal seam, underground dressing of coal and gangue (UDCG), pressure relief and gas drainage before extraction, and backfilling and mining of the protected coal seam.
In order to achieve safe and efficient coal extraction in ultrathick coal seams with thicknesses ranging from 14 to 20 m, the authors propose a fully mechanized large mining height longwall topcoal caving mining method (thereafter LLTCC mining method), developed a full range of technologies and equipment for a LLTCC mining operation.
