Development and Application of Intelligent Ventilation Platform for Metal Mines
In order to solve the prominent problem of lagging regulation and control of metal mine ventilation systems,an intelligent monitoring system of mine air flow is established by setting the monitoring sensor of mine air flow parameters reason-ably.An AI algorithm model of the mine ventilation system is constructed by adopting the deep learning method,then the mine ventilation three-dimensional simulation system simulation database is used to train and test the AI algorithm model,therefore,an intelligent perception system of wind flow parameters was formed.The multi-attribute decision-making theory and method are applied to establish the intelligent control system of the mine ventilation system according to the regulation and controlling re-quirements of mine air demand.Based on the principle of mine intelligent ventilation,the metal mine intelligent ventilation sys-tem architecture and the intelligent control method is proposed,which including the mine ventilation three-dimensional simula-tion system,the air flow monitoring system,the intelligent perception and decision-making system and the intelligent control system,and an operation and control software platform of mine intelligent ventilation system is developed.The results of practi-cal engineering application in a metal mine show that the mine intelligent ventilation system can intelligently perceive the air flow parameters in the operation area in real time,and the error is less than 5％,which has solved the key technical problems of restricting the construction of intelligent ventilation system in metal mines;the real-time dynamic intelligent control of the mine ventilation system,the real-time monitoring and the early-warning and forecasting at fire risk points of the mine,the one-click anti-wind of the main fans,and the statistics and analysis of mine ventilation data can also be achieved.The study results is of great significance for ensuring the orderly flow of mine air flow,ensuring the stable and reliable operation of mine ventilation system,effectively preventing mine poisoning and asphyxiation accidents,and saving ventilation energy consumption.
