摘要
侏罗系下花园组含煤岩系是冀西北张家口地区分布最广、规模最大,煤层发育较稳定,资源储量最丰富的含煤岩系,已探明的煤炭资源储量占全市总储量的65.51%。分布位置主要为尚义-赤城深断裂以南的尚义、宣化、下花园、赤城、怀来、涿鹿、阳原、蔚县等县区内。主要煤田有蔚县煤田、宣下煤田、尚义煤田及赤城煤田。本文对其地质特征及聚煤模式进行了分析探讨,对该区进行煤炭资源勘查具有一定的指导意义。
Jurassic Xiahuayuan group of coal - bearing series is the most widely distributed, the largest, rela- tively stable coal seams development, and the most abundant resources reserves in Zhangjiakou area of northwest of Hebei province. The proven reserves of coal resources are sixty -five point five percent in the total reserves of the whole city. Distributed positions mainly are Shangyi, Xuanhua, Xiahuayuan, Chicheng, Huailai, Zhuolu, Yan- gyuan, Yuxian and other counties in the south of the Shangyi -Chicheng deep fracture. Main coalfields have Yuxian coalfield, Xuanhua -Xiahuayuan coalfield, Shangyi coalfield and Chicheng coalfield. Analyzes and discusses the geo- logic feature and the coal forming pattern, has certain guiding significance to the coal resources exploration for Zhangjiakou area in northwest of Hebei province.
