Study on the fracture characteristics of thick-hard limestone roof and its controlling technique

Environmental Earth Sciences, 2017
The Taiyuan group is one of the coal-bearing formations in Shanxi Province, in which coal resource is extremely abundant. No.15 coal seam is the main minable coal seam in Taiyuan group, and it develops with thick-hard limestone roof which is a threat to safe and efficient mining because of the roof failure.
