摘要(Abstract):
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 ProvinceThe main purpose of this blasting research is the limitation of ground vibrationOn the basis of blasting parameter tests and affecting factor analysis,a reliable blasting scheme has been givenThe important factors which affect the shock effcet include burden,spacing,delay firing system,the amount and distribution of explosives used per blastholeThrough the application of the blasting scheme,a good result of ground vibration limitation has been obtained
