摘要
通过分析光面爆破机理，从最优成缝的原则和最优破碎块度两方面分析了光爆中最优炮孔密集系数的取值。计算结果表明，岩石的最优炮孔密集系数为０．９５～１．２０，合理范围在０．７～１．３之间，这与模型试验和工业试验的结果相吻合。文中有关公式和数据可供施工中参考。
Based on the mechanism of smooth blasting and on the principle of optimum forming fissure and fragmentation degree,the value of optimum burden-to-spacing ratio of blastholes is analyzed.The calculation indication that the optimum burden to spacing ratio is 0.95～1.20,and the proper range is from 0.7 to 1.3.The result fits the lab model test and industrial test on working sits.The related formulas and data in the paper may be for reference people on the working sits.
