Study Of The Key Technology Of Water Inrush Emergenecy Rescue VR Simulation System Based On OSG

Based on the analyzing the non-constant flow law of water inrush, water inrushmodel was established through simplifying the process of water inrush point fromnon-constant flow to constant flow, using numerical simulation technology to solvethe spreading process of water, parametric modeling techniques was used to solvethe laneway model, efficient walking roaming program was proposed. Combined thecomprehensive numerical simulation results and mine scene model, inrush waterbody simulation technology was studied based on physics, a detailed study ofcomprehensive water body dynamic simulation method was proposed. GPU-basedmethod was proposed to improve the algorithms of MC（MarchingCubes） and SPH（Smoothed Particle Hydrodynamics）, Based on both surface texture andparticle-based to achieve the true expression of inrush water, with the compositeresult of A*algorithm and navigation mesh-based algorithm, best escape routes ofmine workers during the inrush water spreading process, In this paper the OSG(Open Scene Graph) technology was first applied to mine water inrush studies, asudden emergency water simulation software system was established, and ainstantiated applications was successfully completed in the three underground minesPINGSHUO company. The research results provide a new technique for mine floodprevention, emergency rescue, accident investigation, mine personnel safetyeducation and training.
