　　为了完善贵州区内突出煤的孔隙结构和吸附特性等物理特性，基于煤的孔隙结构和吸附特性对于瓦斯(煤层气)抽采与防治煤与瓦斯突出的重要性，采用相关仪器测定了贵州突出煤的孔隙结构和吸附特性，并分析了实验结果。结果表明：突出煤样平行层理表面均存在一定数量的晶体物质和微孔；突出煤样垂直节理表面可见一道或几道平行或交叉的且大小不一的裂隙；突出煤样的孔隙或裂隙孔径大部分在0~10 nm之间，孔径为3~5 nm的微孔在煤样中最为丰富，为瓦斯(煤层气)主要吸附空间；当相对压力达到0.8左右时，瓦斯吸附量会急剧上升；突出煤样瓦斯吸附量存在较大差异，孔容大的吸附量大。

In order to improve the understandings of pore structures and adsorption properties of out-burst coal mined at typical mining fields in Guizhou Province, such structures and properties are tested by using related apparatuses based on their importance on the extraction of coal gas (coalbed methane) and the prevention coal and gas outburst of happening. Results show that a number of crystal materials and micropores exist on the surface of coal samples’ parallel beddings;one or several fractures in paral-lel or intersected with different sizes can be observed on the surface of samples’ vertical joints. The dis-tribution of diameters of sample’s pores or fractures is mostly from 0 to 10 nm, and micropores with a diameter of 3 nm to 5 nm are the most abundant in coal samples, which are also the main spaces to ad-sorb the coal gas. When the relative pressure reaches about 0.8, the gas adsorption volume would increase greatly. The gas adsorption volumes change for different samples, generally, the bigger pore volume has more adsorption volume.
