通过对四川省地质构造后期演化及其变形特征的综合研究,结合主要含煤岩系分布及聚煤特征,将四川省赋煤构造单元划分为川南-黔北、华蓥山、米苍山-大巴山、龙门山、川中、大凉山-攀枝花、盐源、巴颜喀拉、西秦岭9个二级赋煤构造带。以构造研究为主线,根据主要含煤岩系和煤层赋存特征与构造形态之间的关系,结合野外实地调查、煤田地质勘查资料以及典型控煤构造特征分析,研究区控煤构造可划分为5大类14种类型,虽然构造样式丰富,类型多样,但主要以挤压构造样式的褶皱断裂组合和逆冲断裂组合为主,其它各类构造样式虽有发育,但数量较少,规模一般也不大。
通過對四川省地質構造後期縯化及其變形特徵的綜閤研究,結閤主要含煤巖繫分佈及聚煤特徵,將四川省賦煤構造單元劃分為川南-黔北、華鎣山、米蒼山-大巴山、龍門山、川中、大涼山-攀枝花、鹽源、巴顏喀拉、西秦嶺9箇二級賦煤構造帶。以構造研究為主線,根據主要含煤巖繫和煤層賦存特徵與構造形態之間的關繫,結閤野外實地調查、煤田地質勘查資料以及典型控煤構造特徵分析,研究區控煤構造可劃分為5大類14種類型,雖然構造樣式豐富,類型多樣,但主要以擠壓構造樣式的褶皺斷裂組閤和逆遲斷裂組閤為主,其它各類構造樣式雖有髮育,但數量較少,規模一般也不大。

Through a comprehensive study on structure later evolution and deformation features in Sichuan Province, combined with main coal-bearing strata distribution and coal-accumulation characteristics have divided coal hosting structural element into 9 second-ary belts of southern Sichuan-northern Guizhou, Huayingshan, Micangshan-Dabashan, Longmenshan, middle Sichuan, Daliangshan-Panzhihua, Yanyuan, Bayan Har and western Qinling. Mainly from structural studies, relations between structural forms and main coal-bearing strata, coal seam hosting features, combined with field investigation, coal geological exploration data and typical coal control-ling structure feature analysis have divided coal controlling structure into 5 categories and 14 types. Although there are abundant struc-tural patterns and types, but mainly have compressive structural pattern fold and fault combination and thrust combination, less other structural patterns with small scales generally.
