Innovative Data Processing Method to Calibrate Mine Ventilation Network Models

摘要

#$%^&*AU2017201934A120181115.pdf#####Abstract An innovative, simple and effective data processing method is provided to calibrate mine ventilation network models. The main processes of this method are: obtaining original airflow quantities and ventilation resistances through consulting ventilation survey report, establishing equations based on Kirchhoff's second law, setting constraint conditions for simulated airway resistances, solving the objective function and obtaining the revised ventilation resistance data. The ventilation resistance data that calibrated through this precise, convenient and economic method will make simulated airflow distribution results perfectly in accordance with the on-site measured data. 1
