Abstract

The invention provides a multi-granularity ore body three-dimensional modeling uncertainty expression and transmission method. Based on an uncertainty reasoning network, a geostatistics Kriging algorithm and a sequential inertial Gaussian simulation algorithm, the multi-granularity ore body three-dimensional modeling uncertainty expression and transmission method concludes and summarizes reasoningtype uncertainty and calculation type uncertainty generated by errors in a modeling process, analyzes the algorithms, establishes an uncertainty expression and transfer model framework of a multi-granularity ore body three-dimensional attribute model in combination with error distribution and transfer conditions in the ore body three-dimensional model establishment process, and realizes quantitative analysis of the uncertainty of the ore body three-dimensional model. The beneficial effects of the multi-granularity ore body three-dimensional modeling uncertainty expression and transmission method are that the multi-granularity ore body three-dimensional modeling uncertainty expression and transmission method achieves the description of the uncertainty expression and transmission process ofthe three-dimensional model of the ore body, and provides a theoretical basis for the design, planning and production of a mine enterprise through employing the three-dimensional model.

Description

technical field [0001] The invention relates to the technical field of three-dimensional geological modeling of mines, in particular to a method for expressing and transferring uncertainties in three-dimensional modeling of multi-grained ore bodies. Background technique [0002] The modeling process of the 3D model of the ore body is affected by the complexity of the mine structure, the incompleteness of geologists' cognition of the ore body, and the sparsity of exploration data. Uncertainty has become its inherent attribute and runs through the ore body. throughout the modeling process. At present, the propagation and quantitative description of uncertainty in the whole process of 3D ore body modeling are still unresolved problems, especially the error calculation method, correction mechanism and its implementation technology are still in the exploratory stage. Contents of the invention [0003] In order to solve the shortcomings of the research on the uncertainty expres...
