摘　　要：根据扩容机理,建立了扩容爆破的物理模型,并且根据动量守恒定律得到了不同条件下最终炮孔挤压区域的半径公式。利用这些公式结合炸药和岩石的特性,以及装药参数得到了扩容结果。理论计算结果与试验数据相吻合。这些结果将有助于爆破扩容理论的完善以及该技术发展和推广应用。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.
