摘　　要：川西高原具有地形高差显著、板块活动强烈、山地灾害频发、生态环境敏感、气候条件恶劣、深部不良地质突出、施工保障困难等特征。通过立轴式钻机与全液压钻机在高原复杂山区深孔钻探的基础数据,对两者在同一环境和地质条件下购置和运维成本、性能特点、完成工作量、钻进效能、环境适应能力、处理事故能力、综合经济效益等方面进行对比,分析各自的优劣势,得出结论:全液压钻机在劳动强度、安全防护、安装运输、自动化智能化方面具有明显优势,工作更平稳,钻效更高,更能节约成本,从而实现了安全、高效、经济的施工。在高原高海拔深孔、超深孔地质勘探工作方面可推广。The Western Sichuan Plateau is characterized by significant topographic elevation differences,intense plate activities,frequent mountain disasters,a sensitive ecological environment,harsh climate conditions,prominent deep-seated adverse geology,and difficult construction support.Based on the basic data of vertical-spindle drills and full-hydraulic drills in deep-hole drilling in the complex mountainous areas of the plateau,this paper compares the two types of drills in terms of purchase and operation and maintenance costs,performance characteristics,workload completed,drilling efficiency,environmental adaptability,accident-handling ability,and comprehensive economic benefits under the same environment and geological conditions,analyzing their respective advantages and disadvantages.The conclusion is that full-hydraulic drills have obvious advantages in terms of labor intensity,safety protection,installation and transportation,and automation and intelligence.They operate more smoothly,have higher drilling efficiency,and can save more costs,thus enabling safe,efficient,and cost-effective construction.This can provide a reference for geological exploration of deep and ultra-deep holes at high altitudes on the plateau.
