摘要
自由面是影响爆破效果的重要因素之一。总结了自由面面积和数量对爆破振动及爆破效果的影响。冲击试验表明,自由面有利于改善爆破效果,研究结果对工程实践有一定的参考价值。
Free surface is one of the key factors influencing blasting effect. The influence of ares and quantity of free surface on blasting vibration and effect are summarized. The impacting test conducted indicates that free surface contributed to improve blasting effect. The research results have some reference value to engineering practice.
