摘 要:针对庞庄矿7431综放工作面实际情况,沿采空区倾向布置4个测点,对采空区气体成分进行测定,采用三次样条插值的方法,按O2、CO浓度确定采空区"三带"的宽度、具体范围及遗煤处于氧化带的时间,最后根据"三带"范围确定了现场防灭火技术的实施工艺,有效防治了采空区遗煤自燃,保证了工作面的安全回采。According to the actual condition of the 7431 fully mechanized caving face in Pang Zhuang mine ,4 measuring points are arranged along the goaf and the gas composition in goal is measured. With the method of cubic spline interpolation,the width specific scope of the "three zones" in goaf and the time of the residual coal in oxidation zone are determined according to the concentration of 02, CO. At last, the implementation process of fire prevention technology at the scene is determined according to the scope of "three zones", which effectively prevents the spontaneous combustion of residual coal in goal and ensures the safe extraction of the coal mining face.
