中文摘要：
煤是一种非均匀多孔隙介质,其孔隙特征及其发育程度与煤层中瓦斯的吸附解吸特性及流动特征密切相关。为探讨型煤的孔隙结构,实验以颗粒粒径分别为4.00～1.70mm、1.70～0.38mm及0.38～0.18mm的煤颗粒制作而成的型煤为研究对象,利用CF-2000P偏光分析软件和Fractalfox2.0分形分析软件对由不同粒径煤颗粒压制成的型煤孔隙特征及发育程度开展了系统研究。结果表明,随着型煤颗粒粒径逐渐减小,型煤中的孔隙半径逐渐减小,孔隙总数逐渐增多,分形维数值逐渐增大,孔隙发育程度逐渐增大,孔隙分布均匀程度逐渐增大。
英文摘要：
Coal is a non-uniform porous medium.The degree of porous development is closely related to absorption-desorption characteristics and flow characteristics of coal seam gas.In order to investigate pore structure of briquette,it is studied the characteristics of porous development of briquette with different coal particle sizes like 4.00～1.70 mm,1.70～0.38 mm and 0.38～0.18 mm by using CF-2000P polarization analysis software and Fractalfox2.0 fractal analysis software.Testing result shows that with the decrease of coal particle size,briquette pore radius decreases,the total number of pores and fractal dimension increase.And the more the pore develops,the more uniform the pore distributes.
