摘　　要：在鱼卡煤田大量野外地质调查基础上,分析鱼卡煤田各区块构造特征及与煤层发育特征,总结控煤构造样式,并进行了构造控煤过程分析,认为鱼卡煤田以褶皱断裂型控煤构造样式为主要特征,经历燕山中至中后期的构造沉降期(原始聚煤盆地发育期)、燕山晚期的构造挤压变形期(控煤构造发育形成期)和燕山期后的构造破坏期(煤层后期破坏作用期),区内沿逆断层发育的地方为勘查重点,尤其是背斜部分,逆冲断层将含煤地层变浅,利于开采。Based on a large number of field geological surveys in Yuqia coalfield, analyzes the tectonic characteristics and coal seam develop characteristics of Yuqia coal field,and summarizes the coal control structure, analyzes the coal controlling process. It is concluded that Yuqia coalfield is controlled by the structural model of the rupture and fracture type, and through to the tectonic subsidence period（the development period of the original coal-accumulating basin） in the middle and late Yanshanian period, the tectonic deformation period of the Yanshanian period（the formation period）, and the Yanshan period after the tectonic failure period（coal seam failure period）, the area along the reverse fault development of the place for the exploration focus, especially the anticline part, the thrusting of the coal strata shallow, conducive to mining.
