摘　　要：随钻地质探测系统是井孔中实现地质导向的关键工具,能够将钻进前方未知地层信息进行实时探测和解析,引导钻孔轨迹方向朝目标区钻进。针对煤矿井下空间狭小、钻具规格尺寸小等因素,开展了小型化随钻地质探测系统结构设计,通过模拟分析设计了外径为φ89 mm的主钻铤,具有结构紧凑、高强度等特性,满足随钻地质探测系统机械结构强度同时,实现了随钻地质探测系统方位电磁波测量单元、方位伽马测量单元和轨迹测量单元的小型化、一体化和模块化设计。The geological exploration system while drilling is a key tool for achieving geological guidance in boreholes,which can real-time detect and analyze unknown geological information ahead of drilling,and guide the direction of drilling trajectory towards the target area.In response to factors such as limited underground space and small specifications of drilling tools in coal mine,a miniaturized geological exploration system structure design was carried out.Through simulation analysis,a main drill collar with an outer diameter of?准89 mm was designed,which has the characteristics of compact structure and high strength,meeting the mechanical structural strength of the geological exploration system while realizing the miniaturization,integration and modular design of the directional electromagnetic wave measurement unit,directional gamma measurement unit and trajectory measurement unit of the geological exploration system.
