摘　　要：以黄白茨煤矿021005工作面为研究背景,通过数值模拟、理论分析和现场实践等手段,对采空区氧化带受工作面供风量影响规律进行研究,研究结果表明:工作面最佳供风范围是763~865 m^(3)/min,在工作面回采中以最佳供风量为参考,在工作面经过上覆3处温度异常点时使用风筒布及木板对顶板加固处理并喷洒罗克休封堵漏风通道,实现工作面安全回采。In Huangbaici coal mine 021005 working face as the research background, by means of numerical simulation, theoretical analysis and field practice, goaf oxidation zone affected by the working surface for air law study, the research results show that the working face is best for the wind range is 763 to 865 m^(3)/min, in mining face with best quantity for reference, in working face through the upper 3 temperature anomaly points when used the ram cloth and wood roof reinforcement and spraying rocsil foam to block air leakage passage, realize safe mining of working face.
