【Abstract】 In this paper,the propagation of linear cracks intersecting a borehole is described infracture control process. The relation in control blasting among parameters , rock strength, tockfracture toughness,behaviour of explosive,etc. is developed.As a result, the methed is obtained toincrease the distance between boreholes to the greatest extent.更多还原
