摘要
通过对泥页岩的风化演变规律及其稳定性分析 ,初步探索了在泥页岩红色地层中的钻眼方法 ,并介绍采用螺旋肋骨钎头和泡沫冲孔技术 ,以及对开挖和衬砌工序进行合理安排的情况。
This paper makes an approach to drilling methods in red shale based on weathering features of red shale with the application of helical rib bit and foam punching technique and reasonable arrangement of tunnel exeavation and linling working procedure.
