Recently, the technical team of CCTEG Xi'an Research Institute successfully developed the "3D visualization simulation platform for mining and excavation ". This is another major technical breakthrough made by the technical team after the development of the mining/excavation monitoring system. The advent of the platform provides scientific data and technical support for high-precision structural exploration and geological modeling of transparent working faces in coal mines.
The 3D visualization simulation platform for mining and excavation uses GPUs to achieve two orders of magnitude acceleration ratio, and the calculation efficiency is 100 times higher than the original; At the same time, the visualization of seismic wave propagation is realized based on VTK technology, which makes it very convenient for researchers to analyze the wave field propagation mechanism under different seismic sources and different geological structures. In addition, the platform can also be used for the numerical simulation of concentrated force source, shear force source, drum shearer, horizontal axis/vertical axis boring machine and other seismic sources, and realize the numerical simulation of wave fields such as trough wave, mining, excavation, micro-earthquake, surface earthquake, VSP and inter-well earthquake.
The platform provides an efficient and convenient tool for researchers to study the seismic wave propagation mechanism corresponding to different types of acquisition, boring machine (such as longitudinal axis, horizontal axis) and other seismic sources, and the wave field response characteristics corresponding to different geological structures (entry fault, collapse column, stress concentration area and crushing zone, etc.). It provides a basis for new intelligent detection technologies such as mining, digging and drilling in the observation system layout, acquisition parameter setting, processing technology research and development, etc., and will effectively promote the progress of new technologies.
With the launch of the platform, researchers and engineers engaged in the new field of intelligent detection will conduct 3D seismic wave numerical simulation experiments more efficiently, develop more accurate intelligent detection technology, and provide more scientific data and technical support for the establishment of high-precision geological models on transparent working faces.
