煤田勘探钻孔中的断层破碎带辨别探讨

Discrimination and discussion on the fault fracture zone in the exploration drilling in coalfield

文章通过多年对钻孔中断层破裂带的分析研究,总结出了如何在钻孔中从破裂带的颜色、成份、结构、构造等要素识别断层破裂带,为构造分析、地层层位对比和寻找断失煤层提共了充足的、正确的方法。深入研究断层破碎带的性质,对地质找矿具有一定的指导意义和现实意义。

Through the analysis and research of the fault fracture zone in drilling during many years,this paper summarizes that how to discriminate the fault fracture zone from colour,composition,structure and other elements in the process of drilling,which provides various sufficient,correct methods for analyzing structure,contrasting stratigraphic horizon and finding broken lost coal seam.This paper also further studies the properties of fault fracture zone,which processes a certain guiding and practical significance.
