The Research And Implementation Of Mine Ventilation Network Calculation And Diagnosis

Mine ventilation is an important part of the production under a mine. A safe, reliable, economic and practical mine ventilation system is important in guaranteeing the safety in production under a mine. At present, the safety management of ventilation can't accurately get safe information of ventilation in time yet and will also delay all kinds of important decisions. So, the development of Computer-Aided Calculation of mine ventilation network and monitoring exceptional data analysis expert system online can improve the ventilation management level and strengthen the anti-disaster ability of mine.The relative principles of mine ventilation network calculation are introduced and how to store mine ventilation network and calculate in computer is studied. The relative principles of expert system, its characteristics, advantages and the differences between expert system and routine system are also introduced. The knowledge expression method and the method of knowledge check and refinement are further studied. The expression method of production rule and its basic elements are expatiated and the knowledge integrality and consistency detection are discussed. The functions of the inference engine are described and the tactics of inference engine control and conflict clearing up are studied too. After the ventilation network calculation, knowledge base and inference engine are studied, the ventilation network calculation and dignosis system based on Windows is developed using Visual C++ language and combining with an instance of mine ventilation network.
