| 摘 要： | 利用扫描电镜、压汞法、低温氮吸附和等温吸附试验对韩城地区煤岩样品的综合分析,探讨了韩城地区构造煤孔隙特征。研究表明：同一煤级,碎裂煤层理、裂隙发育,在富水文地质单元等条件影响下多被矿物质充填,孔隙连通性变差;碎粒煤、糜棱煤显微构造、外生裂隙发育,气孔大量出现促使渗流孔隙显著恢复,隔水性能强造成矿物质变少,孔隙连通性变好...

| Abstract: | Using scanning electron microscope,low-temperature nitrogen and isothermal adsorption,coal sample of Hancheng were tested and analyzed,and pore structure for tectonic coals was discussed.The results indicate that in the same coal rank,stratification and crack are well developed in cataclastic coal,which is mostly filled by mineral substance in the geohydrologic element abundance,results in pore connectivity variation.Granulated and mylonitic coal being of these characteristics,as develope microstructures an... |
