摘要
分析了高瓦斯综放工作面瓦斯涌出机理和瓦斯涌出特点,在此基础上阐述了治理高瓦斯工作面瓦斯超限的有效途径,并对将来进一步治理综放工作面瓦斯提出了一些努力方向。
This article analyzes the gas inflow mechanism and characters in fully mechanized longwall faces with top coal caving where gas inflow rate is high. The article proceeds to discuss the effective ways to control the over-limit concentration of gas in coal faces with high gas inflow rate. The article finally gives some directions in which measures are to be taken to further combat mine gas inflow in fully mechanized longwall faces with top coal caving in the future.
