摘要
通过对云南普朗铜矿的工程地质条件调查和相关的矿岩力学性质试验,获得了表征矿岩工程质量的多种指标,在分析了这些指标后,分别建立了按高程和勘探线划分的可崩性分级模型,应用Laubscher崩落图法分别对高程和勘探线分级模型进行矿岩可崩性评价,计算出可崩性模型的初始崩落水力半径和持续崩落水力半径。通过评价结果的分析表明云南普朗铜矿属于易崩落岩体,适合应用自然崩落法进行开采。
Through the survey of engineering geology and the measurement of crustal stress and field stress in Yun-nan Pulang copper mine,several kinds of indexes representing the engineering quality of rock mass in mines were acquired. After analyzing those indexes, building the hierarchical model on the basis of the elevation and explora-tion line respectively,by using Laubscher’s caving chart to assess cavability of orebody, and to figure out the models of the initial caving hydraulic radius and the continuous caving hydraulic radius. It can be found out by the assess-ment result that Yunnan Pulang copper mine is suitable to be mined by the block caving method.
