Based on the theory of cylindrical charge blasting carter, on-site blasting carter test with variable depth and variable hole spacing were designed and carried out to determine the optimal burial depth and blasting hole spacing. The determined blasting parameters were applied to the coarse sandstone bench of a large open-pit mine in Inner Mongolia. The results indicate that the optimal burial depth range for the cylindrical charge is 1.10 m to 1.16 m, where the energy utilization rate of the charge is high and the volume of the blasting crater is large. The detonation of adjacent cylindrical charges will generate stress wave superposition effect, which gradually weakens and disappears with the increase of hole spacing. The optimal hole spacing is 1.28 m to 1.60 m. The field application results show that the overall shape of the blasting pile is gentle slope, the rock fragmentation is uniform, and the shoveling efficiency is high. Research has confirmed that conducting cylindrical charge blasting crater tests has a guiding significance for optimizing blasting hole network parameters.

基于柱状药包爆破漏斗理论,设计并开展了现场单孔柱状药包变孔深和变孔距爆破漏斗试验,得到了较优的药包埋深和爆破孔间距,并将试验确定的爆破参数应用于内蒙古某大型露天矿山粗砂岩台阶。结果表明:药包较优埋深范围为1.10~1.16 m,此时药包能量利用率高,爆破漏斗体积大;相邻柱状药包起爆会产生应力波叠加效应,随着孔间距增大,叠加效应逐渐减弱直至消失,较优孔间距为1.28~1.60 m。现场应用结果表明,爆堆整体呈缓丘状,岩石破碎块度均匀,铲装效率较高。研究证实开展柱状药包爆破漏斗试验对爆破孔网参数优化具有指导意义。
