From the bottom up, the strata are the Fuxian, the Yan'an, the Zhiluo and the Anding Formations. In the past, it was thought that only the Yan'an Formation contains coal in the Jurassic systerm of the basin. However, recent explorations have shown that the Zhiluo Formation also has some minable coal seams in a certain area.

以往认为鄂尔多斯盆地的侏罗系延安组为含煤岩系，其他均为不含煤的地层，在近几年来的勘查中，发现直罗组也存在具有一定分布面积的可采煤层，笔者通过直罗组岩石露头、钻孔岩心和测井曲线的分析研究，划分了直罗组沉积相，并探索了直罗组的聚煤规律，对煤层进行了预测。

State Key Laboratory of Coal Conversion, Institute of Coal Chemistry,Chinese Academy of Sciences, Taiyuan 030001The siting of B, Al or Ga and the bridging hydroxyl group in mordenite framework were studied by using ab initio HartreeFock methods. The influence of the presence of B or Ga in the framework on the Bronsted acidity of mordenite was investigated.

用从头计算HartreeFock方法研究了B、Al、Ga等同晶取代进入丝光沸石骨架后可能存在的位置，确定了与电荷平衡质子结合的氧位置，考察了B、Ga等杂原子进入骨架对丝光沸石Brnsted酸性的影响。

Mylonitic coal may develop in the center of strongly deformational belt in pressing tectonic stress field. Since mylonitic coal is limited in a narrow area, biggish area in that tectonic coals of brittle deformation distribute is favorable for CBM exploration. Moat of areas are advantageous for formation of coalbed fractures and increase of permeability in extension stress field, but it is easy to beget dissipation of CBM and decrease of gas content. Therefore, study of structure of gas reservoir should be taken seriously.

研究表明，挤压应力场作用下，在强变形带的中心及其附近，可以形成糜棱煤类构造煤，但糜棱煤分布较为局限；在较大范围内形成脆性变形系列的构造煤，是煤层气勘采的有利区带；拉张构造应力场中，大部分区域内有利于煤层裂隙的形成和渗透率的提高，但易造成煤层气的散失，含气量降低，应重视有利的储气构造的研究。

When the fault throw is relatively small, the shale gouge ratio and clay smear potential are relatively large and shale smear is strong. In addition, the coal layers on both sides of the fault are mainly juxtaposed against shale. Therefore, shale smear and juxtaposition play a key role in the sealing. In contrast, when the fault throw is relatively large and shale smear is relatively weak, juxtaposition is unfavorable for sealing. However, the mylonite resulted from strong cataclasis can act as a seal of the coals. The cementation resulted from underground water activity is of great significance to the sealing ability of the fault. Mylonitic coal layers resulted from faulting occur on both sides of the fault. They are unique reservoirs with low permeability and high displacement pressure and their scales depend, to some extent, on the fault throw, fault properties, the hanging wall and footwall.

结果表明：①当断层落差较小时，断层泥比率和泥岩涂抹潜势值较大，泥岩涂抹效应强烈，且与断层两侧煤层对接的岩石主要为泥岩类，此时起封闭作用的主要为泥岩涂抹作用和断层两侧岩性配置关系；②当断层落差较大，泥岩涂抹作用较弱时，对接越不利于封闭形成，但碎裂作用强烈，沿断层两侧形成的糜棱岩对煤层起到了封闭作用；③地下水活动导致的胶结作用对整个断层的封闭具有重要的意义；④断裂作用形成的糜棱煤沿断层两侧分布，此糜棱煤带是一种低渗透、高排替压力的特殊储层，其规模与断层的落差、性质、上下盘都有一定关系。
