| Abstract: | According to the spring mechanism,the physical models of spring blasting are established,and the radius formulas of the final chamber crushing zone has been given under different conditions by using the laws of conservation of momentum.The spring results can be obtained by combining these formulas with the properties of the explosives and rocks,and charge parameters.A series of experiments on spots agree with the results of theoretical calculation.The achievements will contribute to the developments of springing technology and theory and its applications. |
