摘要
岩石可钻性分级是矿山合理组织生产、提高劳动工效的重要指标,采用正确的岩石可钻性分级方法进行分级是露天开采矿山迫切需要的。针对白云鄂博西矿分布复杂、变质化的火成岩进行了全范围有代表性的取样及物理力学特性试验;开展了牙轮钻穿凿各种岩体的现场测试。研究结果表明,矿岩的可钻性与物理力学特性具有很好的相关性。
The grading of rock drillability is an important index for well organized production and efficient opera-tion in mines so that proper grading of rock drillability is in crying needs in open pit mining. Considering the compli-cated occurrences of Baayan-Obo west deposit and altered igneousrock, a long-range and representative sampling andphysical mechanics characteristic test are conducted, toge（her with a field test of cone drilling in different kinds of rocks. The results show that the rock drillability is closely related with the physical and mechanical property of rocks.
