Optimization and application of spontaneous combustion index gases in NO.13 seam of Liuzhuang mine

摘要：

　　In view of the actual situation of coal solid extraction gas in the NO.13 coal seam of Liuzhuang mine.Gases produced by NO.13 coal seam at different temperature is analyzed by using coal low temperature oxidation experimental device.Combining with indicator gas selection principles, CO is prioritized selection as primary index gas of 13 coal seam, C2H6 as auxiliary index gas and fire coefficient-R2 as auxiliary index parameter to predict coal spontaneous combustion development degree.Theory is derived at the same time the relationship of gas composition in high pumping lane and gas composition in goal Through extracting gas in tube and high pumping lane respectively forecast degree of coal spontaneous combustion of shallow and deep in goaf.

关键词： low temperature oxidation spontaneous combustion index gases high pumping lane
