Pressure on Wall of Hole and Destruction of Rock after Blasting of Water-decouple Charge
This paper analyzes initial shock pressure on hole and dynamic stress distribution in rock of hole after blasting of water-decouple charge. Based on strength theory, rock fracture area around the hole and radius of fracture area and disperse area were studied. Taking a vertical well digging blasting as an example, radius of fracture area was calculated, and cut hole disposed parameter was designed. Finally, the correctness of theoretical analysis was proved from engineering application.
