摘　　要：根据安标国家矿用产品安全标志中心新技术要求,用于钻孔轨迹测量仪器在钻孔内使用的部分,其防爆等级应由原来的煤矿用“ib”级提升到“ia”级。钻孔轨迹测量仪要求具备高精度、智能控制,以保证钻孔轨迹精准定位和消除瓦斯空白带。本文设计了钻孔轨迹测量系统,给出了系统的三大组成部分及功能特点。设计兼顾计数故障和非计数故障,采用三级过流过压保护原理,对探管进行电路设计和参数计算。设计了探管姿态数据采集、存储、通信电路和数据预处理技术,开发了采集软件,配置和处理钻孔轨迹并将数据传输到上位机进行分析成图。此外,还研究了仪器智能自诊断的判断规则,使仪器能够对关键部件性能进行自动诊断并给出提示,提高了仪器使用的可靠性和安全性。经过室内精度、性能测试,煤矿井下实测验证,研制的钻孔轨迹测量仪不仅达到了“ia”级防爆要求,而且具有广泛的钻孔适用性、高准确度的测试数据,以及便捷的操作方式,仪器的自诊断功能实用有效。研究成果为煤矿瓦斯精准抽采提供了新的技术手段,有助于提升煤矿作业效率,保障了作业人员的生命安全。According to the requirements of China Mining Products Safety Approval and Certification Center,the explosion-proof level of the part used for borehole trajectory measurement instruments within the borehole should be upgraded from the original"ib"level for coal mines to"ia"level.The borehole trajectory measuring instrument requires high precision and intelligent control to ensure accurate positioning of the borehole trajectory and to eliminate gas blank zones.The paper introduces a borehole trajectory measurement system,providing the three major components of the system and their functional characteristics.The design takes into account both countable and non-countable fault categories,adopts a three-level overcurrent and overvoltage protection principle,and performs circuit design and parameter calculations for the probe.The design of the probe's inclination and azimuth data acquisition,storage,communication circuit,and data preprocessing technology is developed,along with parameter configuration and borehole trajectory processing acquisition software.Data is transmitted to a mobile APP for analysis and mapping.In addition,the intelligent self-diagnosis judgment rules of the instrument have been studied,allowing the instrument to automatically diagnose the performance status of key components and provide prompts,thereby improving the reliability and safety of the instrument’s use.After laboratory measurement accuracy testing and underground coal mine field verification,the developed borehole trajectory measuring instrument not only meets the“ia”level explosion-proof requirements but also has wide applicability to boreholes,high accuracy in test data,and a convenient operation mode.The instrument’s self-diagnosis function is practical and effective.The research results provide new technical means for precise gas drainage in coal mines,which helps with gas outburst control and ensures the safety of workers.
