摘要
根据漏风阻力定律、流动相似理论和几何相似规律,建立了相似模拟通风系统及采空区模型。模型采用Y型通风系统,用能位测定、示踪技术,研究瓦斯浓度分布等技术手段得出风流在采空区内漏风规律,为准确划分自燃氧化"三带"的范围提供了依据。
According to the air leakage resistance law, flow similarity theory and geometric similar rules, the simulated models of similar ventilation system and goaf were established. With Y-shape venti- lation system, the air leakage law in the goaf was obtained via potential energy measurement, tracing technique and the analysis of gas concentration distribution, providing a scientific basis to accurately di- vide the three-zone distribution of coal spontaneous combustion in the goaf.
