Research On Decision Optimization Problems For Mine Safety And Emergency Management

Minerals are basic energy and important raw materials in China.The mineral industry is an important basic industry that is related to national economic and energy security.Mine accidents are characterized by sudden bursts,wide range of influences,and serious consequences.China’s mines are accident-prone areas,and mine safety has always been the focus of national attention.After a mine accident,due to its harsh environment and complex terrain,it may cause the risk of gas poisoning,dust explosion,ventilation system disorder,burns,landslides,etc.It has serious consequences for the personnel and economy of the mine.Therefore,how to further improve the efficiency of mine safety management is particularly important.Based on the optimization of mine safety management,this study optimizes the prevention of pre-disaster accidents and the supply of materials after mine disasters.The main research contents include:(1)Pre-disaster accident prevention for mines: Conduct research on the safety inspection route planning of mines.As the safety of mines becomes more and more serious,efficient safety inspections of mines become very important.In order to save more time to check the areas to be inspected,we need to effectively reduce the time spent by security personnel on the road.Therefore,we propose a mathematical model that meets the mine’s minimum distance for security personnel.In view of this problem,we considered many factors including the degree of staff exhaustion,the balance of workload,mine topography,maximum working time,and longest walking distance.At the same time,local branching,tabu search and neural network algorithm are proposed to compare and verify the validity of the model.(2)Safety inspection path planning expansion: Fault tree analysis is carried out on the unsafe factors of mine safety inspection.Based on the actual situation of the mine,a multi-objective safety inspection path planning model is established and solved based on multiple factors.The safety level of the area is divided,and the number of security personnel is determined.The repeated inspections in key areas and the uncertainty of inspection time are considered,which makes the mathematical model become more more suitable for the actual situation of mine underground safety inspection.(3)Facing the supply after mine disaster: research on the location of mine emergency facilities under natural disasters.Due to the particularity of mining enterprises,the population distribution is relatively concentrated.Under special disasters,mines have corresponding emergency plans,and the key is emergency rescue and replenishment.We consider the damage of emergency facilities under sudden disasters.At the same time,taking into account the different stress resistance factors in each affected area,it is more in line with the actual situation on the spot.The corresponding mathematical model was established and two solving strategies were proposed to provide a more efficient solution for emergency rescue.(4)A decision support system for mine safety and emergency management is proposed for the overall safety of mines.Considering that the mining enterprise is an organic whole and needs coordinated scheduling,we have proposed a comprehensive system platform including decision support system,personnel positioning system and mine early warning system.Collect relevant information of the mine to the system platform and upload it to the database;using the corresponding mathematical models and algorithms embedded in the system platform to make decision calculations,and provide guarantee for the safe production of the mine.In summary,this study has carried out a systematic research on the optimization of mine safety and emergency management.The optimization of security management based on the safety inspection path optimization is studied.According to the actual situation of the mine,the travel time of different links was reduced to improve the efficiency of safety inspection.At the same time,the problem of site selection and distribution of mine emergency warehouses in the event of special disasters was studied,and different resilience factors and damages in emergency warehouses were considered.Finally,using the system platform to implement.Through the optimization research on pre-disaster prevention and post-disaster rescue of mine accidents,it provides theoretical support for improving the efficiency of mine safety production.
