At present, the superhigh shield (mining height is m) had been developed successfully by Zhengzhou Coal Mining Machinery Group Co., Ltd. In China, Tashan coal mine had done the industrial test successfully, with the average coal seam thickness m by the fully mechanized top coal caving mining method (Ming and Baiyun, 2009).
When planning to develop a new mine, or to extend the life of an open pit operation, mine planners have an alternative mining method to consider: block caving. In the right conditions, the advantages of block caving make it an alternative that is now being considered more often.
Openings in a blockcaving mine are subject to high rock pressure. Drifts and other openings, therefore, are excavated with the smallest possible section. Nevertheless, extensive rock bolting and concrete lining is required to keep the openings intact. Properly applied, blockcaving is a lowcost, productive mass mining
Starting around 1900, mechanization was applied to this method. By 1940, some referred to longwall mining as quot;the conveyor methodquot; of mining, after the most prominent piece of machinery involved. Unlike earlier longwall mining, the use of a conveyor belt parallel to the coal face forced the face to be developed along a straight line. The only other machinery used was an electric cutter to
