Mining Safety of Longwall Top-coal Caving in China
2Zhangji Coal Mine, Xuzhou Mining Bureau, Xuzhou 221147, Jiangsu Province, P.R of China ABSTRACT Longwall top-coal caving technology has developed rapidly in China, in recent years. The application of longwall top-coal caving can double both the productivity and the efficiency of a working face and reduce the cost of production by 30 to 40o/o.
A review of cavability evaluation in longwall top
Longwall Top Coal Caving has been considered as one of the most effective technologies for the extraction of underground thick coal seams. A large number of studies on the applicability of Longwall Top Coal Caving into new mine sites have linked the success of its application to the geomechanical understanding of the cavability of the top coal.

On top of this, if there are present dams near to the longwall mining site, this could doubly impact the riparian ecosystems as it would have a reduced inflow rate as well as the loss to the underlying rock fracturing. As of 2014, measures were taken by the Australian government to mitigate water impacts from longwall mining.
