EGR便携式钻机是一种全液压驱动、长行程给进的新型钻机。为探讨该钻机的施工能力和在矿产勘查中的适用性，将该钻机应用于北山萤石矿产勘查中，对9个钻孔的钻孔设计、地层岩石级别和施工效率进行分析。研究结果表明：该型钻机具有可拆卸性好、安全性高、单件重量轻、劳动强度低以及施工台效高等诸多优势，值得进一步推广应用；针对该钻机浅层给压难、事故处理动力不足和维修保养不易等方面的问题，提出通过加强配重、配备液压顶管机以及采用绷绳固定等有效措施和建议，取得了良好的效果。研究结果可为该钻机的改进提供参考。

EGR portable full hydraulic drill is a new type of drill rig in recent years.It is a full hydraulic drive， long-stroke feeding power drill，widely used in geological prospecting，to drill trough mineral exploration，railway，bridge and other engineering investigation and hydrogeological exploration.The purpose of this paper is to study the construction capability of this kind of drill and its applicability to exploration in the Beishan Desert Gobi area through practical application，so as to provide more practical reference for the promotion and application of this kind of drill in the industry.This paper introduced in detail the mechanism composition，structural characteristics，main technical parameters of EGR portable hydraulic drill and its application in fluorite prospecting in Beishan area.By comparing with the traditional drill and the same type of drill in various aspects，it is pointed out that this type of drill has many advantages，such as good disassembly，high safety，light weight，low labor intensity and high efficiency of construction platform.In addition，combined with the construction practice of 9 drilling holes in Beishan exploration area，the paper analyzedthe performance of EGR portable hydraulic drill in construction capacity，drilling efficiency and construction cost，etc.At the same time，Beishan is a desert Gobi area，with harsh natural environment and frequent sandstorms，which have adverse effects on the normal operation and maintenance of the full hydraulic drill.In order to test its applicability in the exploration of Beishan fluorite deposit，the paper also points out some shortcomings and application prospects of EGR portable hydraulic drill.
