石灰石矿减振爆破技术研究

RESEARCH ON DAMPING BLASTING ATA LIMESTONE MINE

介绍了减振爆破技术在河北省２６７２工厂石灰石矿的试验和应用。在以降低爆破地震效应为主要目标的研究中，通过参数试验以及对影响爆破效果的主要因素（如起爆方式、底盘最小抵抗线、孔网参数、药量、装药结构等）的详细分析，提出了操作性强的爆破方案，取得了良好的效果。

This paper introduces the application of blasting technique for ground vibration control at a limestone mine in Hebei ProvinceThe main purpose of this blasting research is the limitation of ground vibrationOn the basis of blasting parameter tests and affecting factor analysis,a reliable blasting scheme has been givenThe important factors which affect the shock effcet include burden,spacing,delay firing system,the amount and distribution of explosives used per blastholeThrough the application of the blasting scheme,a good result of ground vibration limitation has been obtained
