太行山东麓煤田中段滑脱构造研究

Study on Detachment Structure of Middle Section of Coal Field East of Taihang Mountains

通过对太行山东麓赋煤构造带中段井田构造的深入研究,认为临城、邢台、隆尧三个矿区的构造成因是重力滑脱运动;重新认识梳理了太行山东麓煤田基本构造形态;矿区内各个井田都是独立的滑脱体、多个滑脱体聚集形成的滑脱体群,覆盖了太行山山前断裂带,断裂的隐伏露头线应向西移动;以滑脱体为主体的井田构造有其特殊性,需要根据其形成机理去解释,传统方法可能导致井田构造解释失真,进而影响到井田经济价值评价和矿井开采。

Based on an in-depth study of the mine field structure in the middle section of the coal bearing structural belt at the eastern foot of the Taihang Mountains,it is believed that the tectonic genesis of the three mining areas,Lincheng,Xingtai,and Longyao,is gravity detachment movement;Reconsidered the basic structural morphology of the coal field in the east of Taihang Mountains;Each mine field in the mining area is an independent detachment body,a group of detachment bodies formed by the aggregation of multiple detachment bodies,covering the Taihang Mountains piedmont faults,and the hidden outcrop line of the fault should move westward;The mine field structure dominated by slip bodies has its particularity and needs to be interpreted according to its formation mechanism.Traditional methods may lead to distortion in the interpretation of mine field structures,which may affect the economic value evaluation and mining of the mine field.
