The Mine Water-inrush And Avoid Disaster Simulation Algorithm Research And Implementation

This paper mainly studies the simulation process of mine water-inrush.Summary of the related rules of water inrush process, including water inrush pointsdistribution, water inrush process evolution rules, water-inrush mode and spread rules,water-flow movement characteristics in the roadways. And this paper also introducesthe geological and engineering factors affecting water inrush, as the theoreticalfoundation of the subsequent simulation algorithm.This research adopts the traverse point of the roadway as a data source,established roadway space topology relations and data structure, analysis of roadwaynetwork connectivity and roadway network weights. And the storage structure of the roadway is optimized, sparse matrix storage method improve the computing andstorage efficiency of the algorithm.According to the design principle of flood disaster avoidance path, water inrushdisaster avoidance algorithm is established. The algorithm based on graph theory andanalysis of roadway network traffic ability. It implements by multiple arbitrarystarting point for the best route algorithm of personnel to avoid disaster.Finally, studies and implements the water-inrush spreading algorithm and theconstraint of total water spreading algorithm. According to the amount of water inrush,water-inrush point，cross section of roadway, slope and length etc., the algorithmsimulates the evolution process of the development of water-flow in the roadways.Simulate the water-flow to spread and to rise, and the analysis of the influence of thewater-inrush.The algorithm realizes the visual three-dimensional expression of water inrush,route for avoiding disaster and provides the basis for safety training etc.
