摘要:Based the analysis of the "3 zones" theory and index of spontaneous combustion in the mined out area, six measured points under which there are air sample collection probe and temperature sensor measuring the air composition and temperature of the mined out area of No 1304 face are arranged along both crossheadings of the mined out area in order to divide the "3 zones" of spontaneous combustion with the combination of the mining situation of No 1304 face in Tangkou coal mine. This present study mainly measures and analyzes the concentration of O2 and the temperature change and takes advantage of the Matlab and Excel to fit the concentration of O2 to determine the range of "3 zones" of spontaneous combustion in NO. 1304 face. Meanwhile, the concentration of CO is also measured and analyzed to determine the most prone location to fire of No. 1304.
