Research and realization on three-dimensional visualization system of coal seam structure in minefield

Abstract

The three-dimensional visualization of coal seam structure in coal mines is the foundation for coal enterprises to implement transparent mining. Existing three-dimensional modeling systems generally have problems such as poor portability and single interpolation methods. Therefore, this paper adopts the development mode of front and rear separation, and designs and realizes a three-dimensional visualization system of no plug-in and strong portable field coal seam structure based on Springboot+Vue+Mysql. The system interpolates the seam elevation in unknown areas using the optimized Crekin interpolation method, uses the Delaunay rule to generate an irregular triangle network on the coal seam surface, and extends the triangle network along the coal seam elevation to generate a three-dimensional seam model based on generalized triprism prism; finally, with the help of Three.js three-dimensional engine, the browser side displays the three-dimensional effect of the coal seam structure of the minefield. The application of this system has certain guiding significance and reference value for coal enterprises to make reasonable preparations.
