Utilizing Particle System to simulate airflow of laneway in underground mine environment

The implementation of 3D visualization of air flow of laneway would make it possible to monitor the direction, velocity, characteristics and quantities of air flow visually and directly. The paper firstly has presented how to build up the topological relation of airflow in a ventilation network, and how to search all airflow simulating routes between the air inlet and air outlet of the ventilation network automatically based on the topological relation of airflow in such a network. Then the moving process of air flow in the laneway can be modeled based on the principle of particle system. Different from traditional modeling methods, this paper analyses the spatial relationship of laneway and air flow, and puts forward to an improved model of representing laneway airflow in underground coal mine environment with Particle System. The particle effect is implemented by the OpenGL library and VC++ platform. The approach introduced in this paper effectively solved the problems of bad real-time effects and high consumption of computing resources while simulating air flow of laneway in underground coal mine environment with traditional approaches and it proved to be effectively applied in the 3D visualization system for coalmines.
