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。 The diagonally interlaced structure in the area can be divided into four grades. Their common feature is that the depression (syncline syncline) is wide and the uplift (syncline anticline) is narrow; the depression area is conducive to the accumulation and preservation of coal seams, and the uplift area is not conducive to the coal seams Accumulation and preservation, and even become a coal-free zone. The variation of coal accumulation and coal seam thickness is controlled by the comprehensive superposition effect of oblique intertwined structures of different grades.
