Research And Implementation Of Mine Roadway Modeling And Visualization Method

Mine production of digital and intelligent digitized mine is the reason.Four-dimensional space in a unified system,scientific and rational integration of various data mining resources,building sets intelligence,graphics,networking,digital integrated production design,production planning,production management integration of the integrated system is the construction of digital where the core of the mine.Three-dimensional visualization of the mine roadway is to create a true three-dimensional digital environment an important part of mine.The spatial location of the mine roadway,the key attribute and spatial topology rendering 3D visualization,can clear,intuitive display all kinds of roadway relationship between the underground.In the actual production process,the establishment of 3D visualization of the mine roadway system,can reflect real-time progress of the mine roadway excavation work,thus ensuring the process of coal mining safety,improve the mining process management level,and create a real-time and efficient mine safe production business environment.This fully demonstrates the importance and necessity of the establishment of 3D visualization of the mine roadway.This paper summarizes the research status of mine roadway 3D modeling and visualization methods.It describes the 3D visualization of the mine roadway key technology.It analyzes the data source and characteristics of the mine roadway,and study the 3D spatial data model,and established a 3D model of the mine roadway.It researches on the model of the various types of mine roadway intersection of construction,the use of technology and methods common multi-point roadway independent modeling,lifting a big impact coincidence degree roadway intersection modeling.Combining with the database theory to design and build the mine roadway database.On the Qt interface to achieve the roadway directly read the data and modeling.Using directly rendering engine OGRE graphics rendering roadway data,conduct real-time 3D visualization of the mine roadway.For scene roam in the virtual mine roadway,the experience of the 3D realism level for mine roadway.On a practical level,verified the feasibility and practicability of the algorithm.
