Abstract

The embodiment of the invention provides an ore grade estimation method and device based on a BP neural network. The method comprises the steps: obtaining the three-dimensional space coordinates of aposition point in an ore to be subjected to grade estimation in an ore deposit, and determining the input information of the BP neural network according to the three-dimensional space coordinates; inputting the input information into the BP neural network, and outputting grade data of the position point; wherein the BP neural network is obtained by training according to the position point sample of the ore and the grade data of the position point sample. Therefore, the evaluation result is more accurate, and the precision of ore grade evaluation can still be ensured when the number of trainingsamples is small.

Description

technical field [0001] The invention relates to the technical field of geological information processing, in particular to a method and device for estimating ore grade based on BP neural network. Background technique [0002] With the rapid development of 3D visualization technology, geological body modeling technology is also developing rapidly. The key problem to be solved in 3D geological body modeling is how to use the known geological information of boreholes to calculate the geological information of unknown areas, that is, how to perform spatial interpolation. [0003] Due to the limitation of manpower, material resources and capital cost, the geological data obtained through drilling and other projects are a series of discrete data with uneven spatial distribution. Therefore, it is necessary to use the known geological data to obtain the unknown geological data through the spatial interpolation algorithm, and then obtain the data information of the entire geological...
