ZY便携式钻机在揭露斜坡单元孕灾条件中的应用

Application of ZY Portable Drilling Rig in Revealing Disaster-Pregnant Conditions of Slope Units

摘要: 为解决传统大型钻探设备在复杂山区斜坡孕灾条件勘查中的应用难题，本文以永州市零陵区为研究区，应用自主研发的ZY-15、ZY-20、ZY-25型便携式钻机，进行覆盖典型斜坡单元的19个钻孔、累计139米的钻探作业。结合钻孔取样及山地工程等手段，识别出5类孕灾斜坡结构，揭示了区内易崩易滑地层的分布特征及4种地质灾害成灾模式。结果表明，ZY系列便携式钻机兼具轻量化、高适配性、钻进效率高及绿色勘查的优势，可有效克服复杂地形作业限制。本研究为地质灾害快速勘查提供了新手段，对推动精细化地灾防控具有重要实践意义。

Abstract: To solve the application difficulties of traditional large-scale drilling equipment in the investigation of disaster-pregnant conditions of slopes in complex mountainous areas, this paper takes Lingling District of Yongzhou City as the research area, and adopts the self-developed ZY-15, ZY-20 and ZY-25 portable drilling rigs to carry out drilling operations with 19 boreholes covering typical slope units and a total drilling footage of 139 m. Combined with borehole sampling and mountain engineering, five types of disaster-pregnant slope structures are identified, and the distribution characteristics of collapse- and landslide-prone strata and four disaster formation modes of geological hazards in the area are revealed. The results show that the ZY series portable drilling rigs have the advantages of lightweight, high adaptability, high drilling efficiency and green exploration, and can effectively overcome the operation restrictions of complex terrains. This study provides a new method for the rapid investigation of geological hazards and is of great practical significance for promoting refined geological disaster prevention and control.
