摘要
在大量试验研究及理论分析的基础上 ,对预裂爆破参数的计算方法进行了修正 ,利用获得的合理试验参数进行现场验证 ,增大了预裂孔距 ,获得了良好的预裂爆破效果。并提出了一些新的思想与工艺参数 。
Based on a large number of experimental researches and theoretic analysis,the calculation method of pre splitting blasting parameters was modified.The reasonable experimental parameters gained were used to test and verify in situ,and pre splitting blasting space could be enlarged,which obtained favorable pre splitting blasting effect.Some new ideas and technical parameters were raised,which effectively solved blasting vibration in Washan Stope of Nanshan Mine.
