摘要
荥巩煤田煤炭资源丰富,受构造格局控制明显。根据煤田构造特点,在以往地质资料进行信息挖掘和再认识基础上,系统研究了荥巩煤田地质构造特征与地质构造形成机制、构造演化史及现存构造格局,建立了荥巩煤田控煤构造样式,将荥巩煤田控煤构造样式划分为压缩构造样式、伸展构造样式、剪切和旋转构造样式、滑动构造样式4大类,纵湾褶皱型构造控煤样式、堑垒型构造控煤样式、单斜断块型构造控煤样式、走滑型构造控煤样式、背斜型重力滑动构造控煤样式、掀斜型重力滑动构造控煤样式6小类。研究指导了煤炭资源潜力预测与评价工作。
The Xinggong Coal Field was rich in coal resources and was controlled by the structural pattern.According to the characteristics of coalfield structure,based on the previous information mining and re-recognition of geological data,the geological structure characteristics,geological structure formation mechanism,tectonic evolution history and existing tectonic pattern of the Xinggong Coal Field were systematically studied,and the coal-control structure style of the Xinggong Coal Field was established.The coal-control structure of the Xinggong Coal Field was divided into four types：compression structure style,extension structure style,shear and rotation structure style,and sliding structure style,vertical bay fold structure control coal control style,and raft foundation type coal control style.The single-slope block-type structure control coal control style,the strike-slip type structure coal control style,the anticline gravity sliding structure coal control style,and the skew type gravity sliding structure coal control style 6 categories.Research guides the prediction and evaluation of coal resources potential.
