通过对阳泉煤田南部临近寺家庄煤矿进行观测，并进行室内压汞试验，系统分析阳泉寺家山等多个矿的3＃煤、8＃煤、9＃煤和15＃煤储层大裂隙发育特征与孔隙结构特征。结果表明，该区煤层大裂隙发育，有利于煤层的渗透率；煤层气解吸与渗流的关键是微裂隙和植物细胞残留大孔隙；渗透率高值区可能位于南峪、白羊岭一带的深部，马鞍山和上马郡头一带的渗透率可能较低。
通過對暘泉煤田南部臨近寺傢莊煤礦進行觀測，併進行室內壓汞試驗，繫統分析暘泉寺傢山等多箇礦的3＃煤、8＃煤、9＃煤和15＃煤儲層大裂隙髮育特徵與孔隙結構特徵。結果錶明，該區煤層大裂隙髮育，有利于煤層的滲透率；煤層氣解吸與滲流的關鍵是微裂隙和植物細胞殘留大孔隙；滲透率高值區可能位于南峪、白羊嶺一帶的深部，馬鞍山和上馬郡頭一帶的滲透率可能較低。

The southern of Yangquan coalfield near Sijiashan coal mine were observed, and some experiments of mercury injection test were did, anatomically analysed 3#, 8#, 9# coal and 15# coal reservoir fracture characteristics and pore structure characteristics of Si jiashan and other mines in Yangquan.The results show that, seam fissures in the area, is conducive to the coal seam permeability;micro fracture and plant cells remain big pore is key to coal bed methane desorption and seepage;is located along deep of Nanyu and Baiyangling, low permeability value area maybe located along Maanshan and Majuntou.
