Method for obtaining grade of material taking element of long mine storage yard, device and storage medium

Abstract

The invention relates to a method for obtaining the grade of a material taking element of a long mine storage yard, a device and a storage medium. In the method, a material rake is advanced from the length direction of the long mine storage yard for material taking, the long mine storage yard is composed of M layers and K segments, and the method comprises the following steps: S1, obtaining storage yard segments contained in a material taking working face according to a real-time position of the material taking working face and a material taking angle of the material rake; S2, calculating thearea of each layer in each segment contained in the material taking working face in the long mine storage yard; and S3, calculating the grade of a material taking real-time element of the long mine storage yard by combining the area of each layer in each segment contained in the material taking working face and the grade of the corresponding element. By adopting the method, on the basis of implementing a three-dimensional grade model of the long mine storage yard, the material taking real-time grade is accurately calculated. The invention further provides a device using the method, and a corresponding storage medium.

Description

Technical field [0001] The invention relates to the field of three-dimensional modeling and quality control of a mine storage yard, and in particular to a method, a device and a storage medium for obtaining the grade of the reclaiming elements of the mine long storage yard. Background technique [0002] The storage yard is one of the indispensable and important parts of cement mines. Its function is mainly reflected in the following two aspects. First, storage function, as a buffer between limestone crushing and raw material grinding; second, homogenization, After homogenization, the limestone grade distribution of the storage yard and the prediction of the reclaiming grade are important factors that affect the subsequent cement production ingredients. [0003] In the early stage of open-pit limestone mines, the method of yard grade information management was to count the ore volume and element grade information of the ore flow of the entire yard passing through the belt scale and ...

AI Technical Summary

Problems solved by technology

[0003] In the early days of open-pit limestone mines, the method of stockyard grade information management was: to count the ore quantity and element grade information of the ore flow passing through the belt scale and cross-belt analyzer in the entire stockyard, and calculate the weighted average of each element grade according to the ore quantity. As the grade information of the storage yard, the result is that the entire storage yard is regarded as a homogeneous model, and the spatial distribution of the grade of the storage yard cannot be grasped; when the subsequent cement production is batched, the grade of the material taken is also a constant value, It is impossible to predict the real-time change of the material grade, which makes the batching inaccurate and the cement quality control difficult
