| 摘 要： | 依据野外地表地质观测及地震、钻探最新的深部地质资料,结合对区域控煤构造认识,运用构造解析、构造应力场及地质力学分析等研究思路与方法,讨论了研究区控煤构造特征、构造样式以及成因。研究结果表明：研究区共有三类六种控煤构造样式,即挤压构造样式（宽缓褶皱、叠加褶皱）、走滑构造样式（反＂S＂型褶皱、＂入＂字型构造）及伸展构造样式（掀斜断块、堑垒构造）,其中以伸展构造样式发育为主要特征;研究区由东南向西北,构造变形强度由强变弱,先后经历了印支期南北向挤压、燕山中期北西向挤压和喜马拉雅期北东向挤压-走滑与北西-南东向伸展断陷作用;晚期形成的正断层不仅破坏了煤层的连续性,而且成为奥灰水储集和运移的主要通道,增大了底板突水的可能性,使煤炭资源开发受到影响。
