徐州九里山矿区属华北赋煤区的徐淮赋煤带，区内构造复杂，总体上为NE-SW展布复式褶皱，并被一系列NE向的断层切割。通过对区内构造特征研究，总结出3大类5小类构造控煤样式，并对其成因及与煤层赋存之间的关系进行了讨论。结果表明：矿区煤系赋存与控煤样式关系密切。弧形构造的前锋带，构造变形强烈，以断裂构造为主要特征，煤系变浅有利于开采，但破坏较为严重，煤矿开采规模较小；复式褶皱内煤系变形不甚强烈，多以单斜产出或发生宽缓褶皱变形，局部煤层有剥蚀或埋深加大，煤层厚度有一定变化，煤系赋存基本稳定，可以形成大面积的勘探开发区块，浅部应成为今后勘查的重点；夹持于大型逆冲断裂间复式褶皱的靠近背向斜的转换位置煤系以复合构造样式产出，煤系有大面积产出之可能，但煤层埋深较大且部分煤系可能遭受破坏，可以作为找煤远景规划之一。
徐州九裏山礦區屬華北賦煤區的徐淮賦煤帶，區內構造複雜，總體上為NE-SW展佈複式褶皺，併被一繫列NE嚮的斷層切割。通過對區內構造特徵研究，總結齣3大類5小類構造控煤樣式，併對其成因及與煤層賦存之間的關繫進行瞭討論。結果錶明：礦區煤繫賦存與控煤樣式關繫密切。弧形構造的前鋒帶，構造變形彊烈，以斷裂構造為主要特徵，煤繫變淺有利于開採，但破壞較為嚴重，煤礦開採規模較小；複式褶皺內煤繫變形不甚彊烈，多以單斜產齣或髮生寬緩褶皺變形，跼部煤層有剝蝕或埋深加大，煤層厚度有一定變化，煤繫賦存基本穩定，可以形成大麵積的勘探開髮區塊，淺部應成為今後勘查的重點；夾持于大型逆遲斷裂間複式褶皺的靠近揹嚮斜的轉換位置煤繫以複閤構造樣式產齣，煤繫有大麵積產齣之可能，但煤層埋深較大且部分煤繫可能遭受破壞，可以作為找煤遠景規劃之一。

The Jiulishan mining area, Xuzhou is situated in the Xuhuai coal hosting belt, North China coal hosting region. Structures in the area are complex, a NE-SW extended composite fold on the whole, and complicated by a series of NE faults. Based on a study of structural features in the area, have summed up 3 categories and 5 subclasses coal controlling structural patterns, and discussed rela?tions between their genesis and coal seam occurrence. The result has shown that relation between coal measures hosting in the area and coal controlling pattern is quite close. The front belt of arcuate structure has been strongly deformed, mainly characterized by faulted structures, shallowing coal measures is in favor of coal mining, but seriously destructed, thus coal mining scope should be rather small. Coal measures deformation within composite fold is not very strong, mostly in the form of monocline or broad and gentle folded deforma?tion. Coal seams have been eroded locally or buried depth deepening, thickness varied but coal measures hosting is basically stable, large area exploration and exploitation blocks can be formed, shallow part should be the exploration highlight. Coal measures in compos?ite fold between large thrusts near the turning position of anticline and syncline appeared in composite structure may have large areas, but coal seam buried depth can be rather deep and part of coal measures possibly destructed, but can be one of prospects for coal pros?pecting.
