摘　　要：为了准确划分高瓦斯综采工作面Y型通风模式下的采空区三带分布,该研究基于能位测定、示踪技术、回风流瓦斯浓度变化和束管检测等技术手段,探讨了高瓦斯综采工作面Y型通风模式下三带分布主要影响因素中的漏风规律。结果表明:Y型通风工作面采空区存在大量漏风的可能性,且漏风可基本分为风速急变区、风速缓变区和风速趋零区等3个区域。In order accurately classify the three zone distribution of the goal in the high gassy fully mechanized coal mining face with Y type ventilation, based on the energy level measurement, tracing technology, air return gas content variation and beam tube measurement and other technical means, the paper discussed the air leakage law in the main influence factors of the three zone distribution in the high gassy fully mechanized coal mining face with Y type ventilation. The results showed that there was a large air leakage possibility in the goaf of the coal mining face with Y type ventilation. The air leakage basically could be divided to an air velocity sharp changed zone, air velocity gently changed zone and air velocity zero zone.
