Coal Mining Technologies Surface mining of coal requires areas of land to be temporarily disturbed, which raises a number of environmental challenges. As coal mining is only a temporary use of land, a rehabilitation or reclamation plan is designed for each mine covering the period from the start of operations until well after mining has finished.

2014-4-6 (1) The mining technology reduces surface subsidence after the coal is mined. Therefore, the effect that mining activities have on the surface environment decreases. Because the solid waste is used to backfill, this resolves the problem of land being occupied by the solid waste, reducing the damage to the landscape.

4 小时前 The advancement of new coal mining technology is a hot topic that scholars all over the world are watching closely. A mining technique with a high rate of coal recovery was introduced in the 20th century and gained popularity in China starting in the 1950s. This technique is known as “gob-side entrance retaining by filling (GERF)” [ 5, 6 ].
