摘　　要：为研究永陇矿区含煤特性及控煤因素,以地勘数据为基础,通过地质资料的分析,开展了研究区含煤特性、沉积环境及控煤因素研究。结果表明:延安组为区内含煤地层;延安组煤层总厚度0.20~16.90 m,平均6.03 m,含煤系数0.18%~38.97%,平均12.95%;区内含煤地层的沉积厚度和分布规模受基底古地貌构造控制,煤层是古地貌控煤和古环境控煤因素共同作用的结果。In order to study the coal-bearing characteristics and coal-controlling factors in Yonglong mining area,based on the geological prospecting data and the analysis of geological data,the coal-bearing characteristics,sedimentary environment and coal-controlling factors in the study area were studied.The results show that the Yan’an formation is a coal-bearing stratum in the area,the total coal seam thickness of the Yan’an formation is 0.20-16.90 m,with an average of 6.03 m,and the coal-bearing coefficient is 0.18%-38.97%,with an average of 12.95%,the sedimentary thickness and distribution scale of the coal-bearing strata in the area are controlled by the basement paleogeomorphological structure,and the coal seam is the result of the joint action of paleogeomorphological and paleo-environmental coal-controlling factors.
