Research on the Three Zones of Y-shaped Ventilation Goaf Based on the"O"Ring Theory
Taking the 9201 working face of Shanxi Yamei Daning Energy Co.,Ltd.as the research object,based on the"O"ring theory,Fluent software was used to numerically simulate and explore the gas distribution characteristics behind the goaf of the Y-shaped ventilation working face.The"three zones"field measurement of the goaf of the Y-shaped ventilation working face was carried out using the bundle tube monitoring method.The measurement results were compared and verified with the simulation results.The error between the numerical simulation results and the field measurement was less than 5%,indicating a high degree of fit between the numerical simulation and the field measurement,which can provide data reference for the implementation of fire prevention and extinguishing technology in the goaf of adjacent working faces in the same coal seam.
