Abstract
This paper gets the parameters of temperature,O2 and CO at different distances of different measuring points in the intake and return side from working face by site buried tube observation in the gob of Yangwangou coal mine 6202 fully-mechanized caving face,and gets the distribution laws of O2 concentration and air leakage intensity in the gob.The hazardous area of spontaneous combustion in Yangwangou coal mine is divided by ＂three zone＂ division method,and the scope of the ＂three zones＂ in the gob of 6202 fully-mechanized caving face is determined.The limited advance speed of working face is determined by the width of the oxidation and heat accumulation zone and the shortest time of floating coal spontaneous combustion.关键词
