Mine Ventilation Information System And Data Integration Research

The mine ventilation system is the guarantee for the safe and efficient construction of the mine.It involves many data,large amount of information,and many influencing factors.The collection and treatment of ventilation information provides a scientific basis for the investigation of mine hidden dangers and the prevention of major accidents.In recent years,due to the distortion of the ventilation management information collection and the mistakes caused by the decision-making process,the accidents are still in time.The main reasons are the dispersal of data in ventilation information management,the existence of “information islands” in data,and the inability to achieve scientific analysis and decision-making.The hidden dangers of ventilation cannot be discovered and corrected immediately,and problems cannot be scientifically determined.Therefore,in-depth study of the informationization and data integration of ventilation systems to achieve digital processing and sharing of ventilation information is of great significance for the realization of digital and intelligent mine management and the construction of safe and efficient modern mines.The research of the thesis is based on the problem of data dispersion and non-uniformity in the ventilation information at present,which seriously restricts the safety of ventilation.The data warehouse technology is used to extract,clean,process and unify the information of mine ventilation system,and to study the construction of mine ventilation information data warehouse.The method and the process of its creation complete the data warehouse logical architecture and technical architecture construction,design the ETL in the mine ventilation data warehouse,and research and design its extraction process and implementation process to realize the standardization of data between different business systems.Integration,breaking the “information island” of ventilation data,and realizing information sharing;at the same time,based on the visualization requirements of mine ventilation information data,the WebGL is used to develop a three-dimensional model of mine ventilation system,and the data warehouse technology is combined to realize the visualization of ventilation information data.The research results were applied to Hanglaiwan Coal Mine,and a mine ventilation data warehouse was established,which was combined with the three-dimensional ventilation system model to realize the integration and three-dimensional preview of ventilation data,which improved the efficiency,quality and scientific decision-making level of ventilation system management.Figure38;Table2;Reference57...
