摘　　要：首先提出台阶岩体爆破的悬臂薄板物理模型，并在此基础上建立了台阶多排微差爆破的炸药量计算公式．经国内１０余家矿山应用和验证，获得了良好效果．The physical model of cantilever board in bench blasting is firstly presented and based on the hypothesis, a formula for calculating the charge weight in the MS delay bench blasting is also derived. It has ben used in tens of mines in the southern and northern China and has got an ideal effect in rock breakage.
