The Research Of Real Time Mine Ventilation Simulation And Airflow Abnormal Value Analysis

In an effort to fit the actuality and requirement of mines, a study on the real-time simulation and airflow abnormal value analysis for mine ventilation systems is put forward on the basis of newly achievements in researches in the field of mine safety. Ventilation in mines is consistently affected by many unforeseen changes in the system. To study on the fluctuation and variation of ventilation, a mathematical model based on the statistics theory and ventilation sensitivity concept is proposed.The study of ventilation reliability and sensitivity in coal mines plus an effective usage of Internet and computer graphics lead to a feasible model of airflow abnormal value analysis, which enables us to find out reasons behind the abnormal values and the possible consequences afterwards. The study of the algorithm and model is verified through its application to a coal mine.The testing software reached the preset goal, showing its good fitness to the practical needs of coal mines. To improve its applicability further, a function of drawing especially designed for mine ventilation network is developed and included. A function of decision-making assistant is also put forward, which has further simplified mine ventilation resistance measurement, the calculation of ventilation sensitivities and the analysis of airflow abnormal values.
