Abstract: Mine B in Yunnan Province is a high gas mine.The ten layers of mineable coal seam are all spontaneous or easily spontaneous combustion coal seams.Based on the analysis and prediction of spontaneous combustion of its coal seam,we put forward the comprehensive fire prevention and extinguishing measures with grout in gas the main part and spraying chemical inhibitor as the auxiliary part.The parameters of grouting and inhibitor are determined,and the model of system equipment is selected.The field practice has achieved the desired results,which provides a reference for the similar conditions of other mines.

Key words: flammable coal seam, grouting fire prevention and extinguishing, inhibitor
