Experiment research on decision of spontaneous combustion zone in goaf on fully mechanized coal face

摘要

By arranging sampling tube in goaf of mine, we measured the gas and obtained the corresponding data. Then according to the application of Fluent numerical simulation technology based on the measured data, the spontaneous combustion zones in goal of fully-mechanized coal face was determined; thereby it provide scientific basis for the work of fire prevention and extinguishing in goal.
