Multiscale Modeling for Fracture Zone with Detailed Division

利用TRT6000超前探测数据与3DMine软件耦合,以切片导出数据的方法,获取裂隙矿段的局地反射系数并确立了数据导出原则和模型构建方法,在矿床数字模型基础上,建立裂隙矿段多尺度精细分区模型。对TRT6000数据导出及在3DMine中建立多尺度精细分区模型的方法进行了研究,并对构建的多尺度精细分区模型进行了进一步分析,结果表明:切片数据处理方法可以建立裂隙矿段不同破损程度岩体的分级并进行精细数字化处理;利用反射系数的分级,实现了岩体破损精细建模,有利于不同矿段的差异化处置与分析,是一种跨空间的多尺度模型。工程应用表明精细化、多尺度模型满足了区域采矿与局地安全的需要。

With the True Reflection Tomography（TRT） 3D image processed by slicing, the generated data was exported and coupled into 3DMine software, resulting in a local reflection coefficient of fracture zone. The principle for data exporting and method for model construction were all presented. Based on the digital model of the deposit, a muhiscale modeling for fracture zone with detailed division was obtained. Then, a further analysis was conducted for such multiscale modeling. Result showed that the process of slicing TRT image can give a classification of degree of rock mass damage in fracture zone. Based on the digital processing, a model with detailed rock mass damage can be constructed with the classification of reflection coefficient, which is also a muhiscale model from the perspective of space, beneficial for processing and analyzing the difference in each mineralized zone. The application into engineering project also indicated such multiscale modeling with detailed division can meet the requirement for regional mining and security in underground mine.
