摘　　要：构造控煤作用是控制地层赋煤的主要地质特征。青海省地处青藏高原北部,主要聚煤盆地构造复杂,控煤构造样式多样。在系统分析总结区内主要含煤盆地构造发育的基础上,按照煤层赋存状态将主要控煤构造分为三类十种,其中以褶皱-断层组合为主,尤以逆冲断层和褶皱共生为特征。通过对控煤构造类型的举例说明,旨在为找煤地质工作提供参考。The structural coal-controlling is a main geological feature to control strata coal hosting. The Qinghai Province is situated at the northern Qinghai-Tibet Plateau; its coal accumulation basins have complex structures with multiple coal-controlling structural modes. Based on systematic analysis and summing-up of main coal-bearing basins structural development in the area, according to coal seam occurrence state, divided main coal-controlling structure into 3 categories and 10 types, in which, the fold-fauh assemblage is the main type, especially characterized by the association of thrust and fold. Through examples and illustration, the paper has provided reference for coal looking geological works.
