| 摘 要： | 以能量平衡准则与岩石波阻抗为判据的岩石爆破性分级方法为依据，结合分析矿岩节理、裂隙和高应变率下的矿岩动载特性，将爆破性一致的矿岩地段划分为一个爆区，以此确定不同的孔网参数和材料消耗定额，优化爆破设计与施工。

| Abstract: | According to the rock blastability classification on the basis of energy balance and rock surge impedance criterion and combining with the analysis on rock Joint, crack and dynamic-load properties of rock under high strain rate, those sections which have identical rock blastability are designated as one blast area. Then, the pattern parameters and material consume norm for each of the blast areas are determined so as to optimize the blasting design and execution. |
