摘要
本文对杉木树煤矿层滑带的特征和分布规律作了观察和研究。利用扫描电镜和X光衍射得出层滑带物质成分的微观表现和组合特征;明确提出层滑构造发育的两个基本力学条件;系统阐述了褶皱过程中地层倾角对层滑强烈程度的控制作用;预测了该矿层滑薄化带的分布范围,为进一步研究层滑构造及其分布规律的预测打下了基础。
The characteristics and distribution regularity of layer-sliding band in Shamushu Coal Mine have been observed and studied. The microscopic expressions and combination features of matter composition in layer-sliding band are obtained with scanning electron microscope and x-ray diffraction. Two mechanics conditions for layer-sliding structure development are pointed out unequivocally. The controlling acton of stratigraphical dip angle on layer-sliding intensity in folding process is explained systematically. The distribution scale of thin-slided band in this mine is predicted. Then the theoretical foundation is laid for further studying layer-sliding structure and predicting layer-sliding distribution
