临界爆点
落锤感度试验时,称爆炸率达50%的落锤高度为临界爆点,也叫冲击感度。在实际应用上,也有把6次试验中有一次发生爆炸的落锤高度叫做临界爆点

load strength or index
集中载荷强度或指数
在现场或试验室测定近似抗压强度的一种方法,以MPa 为单位。集中载荷径向施加于岩心之上。破碎岩石所需之力F和载荷点之间的长度 L〈L = d,为岩心直径〉决定着集中载荷指数 Iₛ,Iₛ = F/d²。试验规程已由 ISRM〈国际岩石力学学会〉于1985年描述

药包在药柱的一个点上起爆。为安全起见,或为提高炸药的效能,可在一个药柱内置放若干个集中药包,形成底部、中部或顶部起爆。起爆可采用雷管,而对非雷管敏感炸药,则可用起爆药包
