Construction of Underground 3D Visualization Model of Mining Engineering Based on Shear-Warp Volume Computer Rendering Technology

Abstract

In view of the complexity of mine geology, complex mountain structure, and strong concealment characteristics, the construction of 3D visual model of mining engineering is of great significance for mine mining design, production, and residual ore remining. Based on the comprehensive analysis of the development results of the existing 3D visualization software of ore body at home and abroad and the actual needs of domestic mines, this paper determines the key technologies and solutions to be studied. Focusing on the overall goal of real ore body visualization, relying on geology, mining, computer graphics CAD technology, and computer software engineering develops a set of 3D visual modeling general components for 3D simulation software developers to realize the 3D visual operation platform of ore body with independent intellectual property rights. By introducing the Shear-Warp volume computer rendering technology into the underground 3D visualization analysis process of mining engineering, a three-layer visualization platform structure based on hierarchical model is designed from the perspective of software engineering, which effectively strengthens the low coupling of data and high cohesion of function of the system. The example analysis results show that this method can accurately simulate the 3D structure and distribution of the actual ore body and make basic preparations for reserve estimation, mining design, mining development, and prospecting prediction. At the same time, the general component of 3D visual modeling provided by the system is ready for the interface of 3D simulation involved in mining software development.
