摘　　要：水平分层采煤法一般应用于厚煤层。对于急倾斜煤层水平分层工作面,瓦斯来源不同于倾斜、缓倾斜煤层,瓦斯源主要以本层下部煤体为主。主要分析了水平分层工作面瓦斯来源,研究并确定了急倾斜煤层水平分层采煤法工作面瓦斯涌出量计算方法。Horizontal slicing method is generally used in thick coal seam. Different from inclined coal seam and gently inclined coal seam ,the gas sources of horizontal slicing working face in steep coal seam are mainly the upper coal seam of the coal seam being work- ing. Analysed the gas source of horizontal slicing working face, gas emission calculation method was also studied and determined on hori- zontal slicing working face in steep coal seam.
