Measuring airflow ＆ evaluating resistance model of the mine ventilation network based on Tikhonov regularization
Abstract：According to the dynamic and complex characteristics of the mine ventilation system, the algorithm of choosing the optimum circuit for the minimum regulation number of measuring airflow and evaluating resistance model was put forward. Combining with the real-time dynamic monitoring data of the air volume, the paper established the measuring airflow ＆ evaluating resistance model of the mine ventilation network based on the monitoring data. Because it easily constructed the ill-posed coefficient matrix while the model applied to the complex network, the solving method of parameters of the Tikhonov regularization based on the greedy algorithm was proposed to revise the model. The application shows that this method can reduce the severity of ill-posed matrix and moderately solve complex ventilation network. It exerts the real-time dynamic monitoring function of the monitoring the basic data to the dynamic simulation of mine ventilation system. the resistance of the system and provides
