Abstract:To address the issues of decision-making delayand insufficient parameter accuracy in traditional anti-wind control during mine fireaccidents,amethod fordynamic simulationofanti-wind efect in coal mine ventilation systems and construction of an airflow regulation parameter databasewas proposed.Taking the ventilation system of Sandaogou Coal Mine in Yulin City,Shaanxi Province as an example,a roadway topology database was established through 3D modeling technology.An improved genetic-ant colony hybrid algorithm was used to solve theventilation network,achieving high-precision dynamic simulation of underground airflow distribution during fireperiods.Through multi-scenario fire simulations,ananti-wind feasibilityevaluation system wasestablished,focusingonparameters such as smoke diffusionpaths,variation coeficientsof wind speed atkey nodes,andanti-wind compliance time.Based onsimulation data,a hierarchical airflowregulation parameter database wasconstructed,and an intelligent mapping of roadway numbering,fire coordinates,and regulation parameters was realizedusing associative coding technology.Practical application showed that the parameter database reduced anti-wind preparation time by 68% and decreased airflow stability standard deviation from ±15.3% to ±5.7% , enhancing the mine's emergency response efficiency to sudden incidents and providing a new paradigm for the application of intelligent ventilation systems in mine disaster emergencies.

Key words: intelligent mine ventilation; anti-wind simulation and calculation; anti-wind airflow regulation; parameter database; genetic-ant colony hybrid algorithm
