摘　　要：在湘西北地区进行滑石矿详查项目中,采用模块化全液压钻机进行钻探施工,穿过多层页岩、泥页岩地层,岩石破碎。本文对钻探施工过程中遇到的钻机能力、冲洗液、钻孔环状间隙等各种技术问题进行了分析,并提出的应对措施,对于同类矿区的施工具有一定的借鉴作用。In the detailed investigation project of talc mine in northwestern Hunan,modular full hydraulic drilling rigs were used for drilling construction,penetrating multiple layers of shale and mudstone formations,and breaking rocks.This paper analyzes various technical problems encountered during the drilling construction process,such as drilling rig capacity,flushing fluid,and borehole annular gap,and proposes countermeasures,which have a certain reference value for the construction of similar mining areas.
