凿石中的岩石质量指数 | rock quality index in drilling |
炸药与岩体的关系被认为是单位炸药消耗量、爆破人员可用来作为确定岩体中炸药分布的总指标 | The relationship between the explosive and the rock mass is known as the powder factor and can be used by the blaster as a general guideline for determining explosive distribution in the rock mass |
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 | point load strength or index |
