Research On Simulation Of Mine Underground Safety Escape Based On Repast

The safe escape of the miners has always been an important problem in the field of coal mining.In past several years,the state has issued series of policies,the strength of the treatment is increased,the death toll of coal mining and the death rate of the million tons are reduced,but the occurrence rate of the mining accident is still higher than that of other countries,The security situation is not optimistic.The mining speed is accelerated,the mining depth is increased,the escape exercise is reduced and so on,which threatens the life of the miner all the time.At present,most of the research on coal mine escape and evacuation at home and abroad abstracts coal mine roadway into homogeneous space,which can not reflect the real geographical space,disaster emergencies,the assistance of safety facilities and the psychological factors of miners.Therefore,there is a great difference between the results of the study and the real situation.In order to solve the above problems,this paper adopts multi-agent simulation technology,based on the theory of bottom-up multi-agent modeling method,through the simulation platform(Recursive Porous Agent Simulation Toolkit,Repast)loose integrated geographic information system(GIS),and takes the Shaqu Mine of Huajin Coking Coal Group in Shanxi Province as an example,constructs the simulation model of coal mine safety escape.First of all,the working environment of the miner is built by using the real data of the landway,and it is displayed in Repast.Secondly,according to the roadway environment,the miner agent,disaster object and disaster relief facility object are abstracted,and the behavior decision-making mode of miner agent is summarized.Third,the Repast simulation mechanism is used to deduct the process of the escape route planning by the miners with the aid of the disaster relief facilities during the occurrence of the roadway disaster.Finally,four kinds of scenario simulation are designed,including chamber simulation,multi-exit simulation,mobile lifeboat simulation and job classification simulation,and the influence of various disaster relief facilities on miner escape rate is analyzed in detail.In this paper,the factors related to the safety escape of miners in coal mining are deeply studied,which provides the basic guarantee for coal mine safety production and coal mine management.First,combining the real geographical data of roadway with computer simulation can effectively solve the practical problems.Secondly,by mapping the disaster objects,disaster relief facilities objects and miners into the computer system,it not only explores the influencing factors and general rules of miners' safe escape,but also helps miners to quickly plan a shortest path to the exit.Thirdly,the escape process can be displayed through the visual graphic interface of Repast,which can deeply understand the unsafe factors in the mine roadway,provide an improvement scheme for the mine managers,and provide decision support for the prevention and rescue of roadway accidents.
