%X Fracture control blasting, a new perimeter control technique, is an alternative to pre-splitting or smooth wall blasting which can be used to achieve better perimeter control results. Its main characteristics include that it uses notched boreholes to predetermine the location of crack initiation and that it employs cushioned charges of low explosives to control the borenole pressure and to intensify the crack-driving effect of explosive gasses. This paper first describes the basic principles of fracture control blasting and then emphatically presents the test results of actually applying this method in roadway excavation and gives a comparison between these results and those of other blasting methods.
