在考虑可崩性区域化评价需要的基础上,选择了完整岩石强度、RQD值、节理间距、节理摩擦角等指标作为可崩性区域化评价的指标体系,并重点讨论了这些指标的数据采集和计算方法。在应用MicroMine软件平台建立整个矿体的三维块段模型的基础上,应用地质统计学的方法对每个块段的评价指标值进行估值,并根据每个块段的评价指标值利用RMR指标估计整个区域的可崩性级别。研究目标是开发一个在三维环境下用来预测矿体可崩性分布的工具。金川III矿区矿岩可崩性分级表明矿岩可崩性属于中等偏上,与生产实际相符,在生产中可应用该方法进行矿岩可崩性分级工作。
Based on the evaluation of avalancheable regionalization, indices such as intact rock strength, RQD value, joint spacing and joint frictional angle were selected as the index system for the evaluation of avalanche regionalization, and the data acquisition of these indexes was mainly discussed And calculation method. On the basis of establishing a three-dimensional block model of the whole ore body by using MicroMine software platform, the method of geostatistics is used to evaluate the evaluation index value of each block, and the RMR index is used according to the evaluation index value of each block segment Estimate the level of disastrousness across the region. The research goal is to develop a tool that can be used to predict the disintegrability of ore bodies in a three-dimensional environment. The grade of mineable rock disintegration in Jinchuan III shows that the mineable rock disintegratability belongs to the middle and upper grade, which is consistent with the actual production. This method can be applied to grade disintegration of ores in production.
