Targeting the simulation of the ventilation network of the mine,it is necessary to quickly determine the ventilation resistance of unmeasured roadways in the ventilation network.The composition of a large database for ventilation roadway resistance coefficient and the method of forming a database cluster were studied,and a method for extracting the friction resistance coefficient of ventilation road-ways based on big data was proposed.Based on a large amount of basic data,the basic properties and environmental parameters of the roadway were fused to quickly determine the resistance coefficient of the roadway foundation,providing a strong data foundation for the rapid construction of ventilation network simulation models.
