【摘要】 使用９３１０型微孔结构分析仪，对煤和煤层顶、底板岩石的孔隙特征作了系统研究，取得下列结论：煤的孔隙发育主要受煤的变质程度、煤岩组分及成煤植物和后期构造破坏等因素的综合控制；碎屑岩的孔隙发育主要受岩石粒度和充填胶结程度控制；灰岩孔隙发育特征主要受溶蚀作用强度控制。更多还原

【Abstract】 Using the micropore structure analyzer of 9310 type,the pore characteristics in coals and roof and floor rocks of seams are studied systematically.It is concluded that pore development in coal is controlled comprehensively by the factors such as metamorphism degree of coal,coal component,coalforming plant and posttectonic rupture;the pore development in detrital rocks is controlled mainly by the grain size of rock and filling and cementing degrees;and the pore development in limestone is controlled mainly by the corrosion intensity.更多还原
