Abstract: This article outlines the purpose of establishing a gas ventilation resistance coefficient database, the composition, functions, and technical characteristics of the database. The roadway frictional resistance coefficient database can be used when the coal mine worker encounters unknown ventilation resistance roadway to construct the mine ventilation simulation network, and then obtain the recommended friction resistance coefficient by matching the roadway basic parameter data in the database system. The database provides a strong basis for the rapid determination of ventilation resistance and the rapid establishment of a ventilation network simulation mode in unmeasured roadways.
