| 摘 要： | 区内斜向交织构造可划分为四级,其共同特点是坳陷(同期向斜)宽阔,隆起(同期背斜)狭窄;坳陷区有利于煤层的聚积和保存,隆起区不利于煤层的聚积和保存,甚至成为无煤区。聚煤作用及煤层厚度变化规律受着不同级次的斜向交织构造综合迭加效应的控制。

| Abstract: | Based on the study of contemporaneous folded structures, this paper discusses the oblique direction interwoven structure framwork and its control on the coal accumulation and preservation in Jiaoping coal mining district.According to the scale,the oblique direction interwoven structures in this region may be divided into four orders, the characteristics of which arc broader in the depressions ( contemperaneous synclines ) and narrower in the uplifts ( contemporaneous anticlines ) , and the depression areas have many advantages over the uplift areas in the accumulation and preservation of coal seams. the coal accumulation and the variation of coal scam thickness are both controlled by the oblique direction interwoven structures in different orders. |
