Development of fractures in soft rock surrounding a roadway and their control
Mining Science and Technology (China), 2011Abstract As the excavation of roadway, new fractures will be formed and the pre-existing fractures extend with the redistribution of stress in surrounding rocks. Eventually, fracture zone and bed separation are formed in rocks because of the developed fractures.
