3号煤层的地质条件与寺河煤矿、赵庄煤矿相似，但瓦斯产量差异较大。为了更好地了解孔隙的影响，采用实验测量和定量分析相结合的方法，对高阶等变质无烟煤的孔隙性质进行了深入研究。研究表明，孔结构以吸附为主，占比表面积的88%以上。赵庄煤矿煤样在1 nm和9 nm(7 Nm)分界点具有典型的三级分维特征，1~9 nm(或1~7 nm)分维值明显大于给定值范围外的分维值。四和矿样的孔隙主要为开放球形或椭圆形，赵庄矿样的孔隙主要为Y型、V型或“墨水瓶”型。
The geologic conditions of No. 3 coal seams are similar to Sihe and Zhaozhuang Collieries, however, the gas production is significantly different. To better understand the effect of pores, by means of experimental measurements and quantitative analysis, the pore properties of high-rank isometamorphic anthracite were thoroughly studied. Our study showed that the pore structures were predominantly adsorptive, accounting for more than 88% of the specific surface area. The coal pores showed typical three-stage fractal characteristics at boundary points of 1 nm and 9 nm (7 nm of coal samples from Zhaozhuang Colliery), and the fractal dimension with 1–9 nm (or 1–7 nm), as being significantly larger than those measured outside the given ranges. Pores in samples from Sihe Colliery were mainly open spherical or ellipsoidal pores in shape; conversely, those from Zhaozhuang Colliery were mainly Y-shaped, V-shaped, or ‘ink-bottle’ type.
