Study On The Best Escape Route When Mine Water Inrush Occurs

As one of the five natural disasters in mines,mine flood has been threatening the safety of mine production.The geological conditions are complex in China,and China is one of the countries with the most serious water disaster in the world.In recent years,with the increase of the mining depth of the mine,the influence of the disturbance on the groundwater is further increased,and the probability of water inrush accident and the intensity of water inrush also showed an increasing trend.In view of the sharp nature of underground flood accidents,in case of flood accident,it should make sure that the tapped personnel evacuate as soon as possible to a safe location in order to reduce the number of casualties.Based on this consideration,this thesis developed a system of mine disaster emergency flood occurs,the system is an important part of safety risk "six systems",can improve the mine's emergency disaster avoidance ability to a certain extent,so it has a certain contribution to the construction of digital mine.The first chapter is an introduction,including the background,purpose and significance of the study,and then discusses the research status at home and abroad.The second chapter is the analysis of mine water filling conditions,including the analysis of the mine water sources,analysis of mine water filling channel analysis of mine water filling strength,mine hydrogeological types and analysis of tunnel water inrush in flow and evolution.The third chapter is the comparison and improvement of the mine water hazard avoidance route.First of all,the paper discusses the principle of disaster avoidance design.Based on the comparison of the shortest path algorithm,the traditional Dijkstra algorithm is selected as the solution.Then according to the specific requirements of mine water avoidance,this paper improves the traditional Stella algorithm,and uses the equivalent path instead of the actual path,which can take into account the efficiency of each roadway.The fourth chapter is the establishment and analysis of the tunnel network model.Firstly,it analyzes the data sources and the characteristics of the network model,and then determines the storage structure of the network parametersThe fifth chapter is the design and implementation of mine water wall system,using Microsoft Visual Studio 2012 as the development environment,using VisualBasic.NET as the development language.Emergency safety system is designed,and then applied to the mine based on the engineering geological materials.
