摘　　要：与石油行业仪器设计相比,煤矿井下仪器最大的区别是需要增加防爆设计。我国煤矿井下普遍含有高浓度瓦斯爆炸性气体,电气电子设备工作存在安全风险,必须对仪器工作电路和结构进行本安防爆设计,使之满足国家矿用产品标准。针对煤矿井下特殊环境,机械结构设计部分有两方面需要重点考虑,分别对强度、性能方面的需求和仪器隔爆接合面的设计,将通过有限元仿真模拟受力分析及实验测试相结合的方法验证其可靠性,为开发适合煤矿井下随钻方位电磁波测井仪器提供参考。Compared with the instrument design in the petroleum industry,the biggest difference in underground instrument in coal mine is the need to add explosion proof design.In China,coal mine generally contain high concentrations of explosive gases,and there are safety risks in the operation of electrical and electronic equipment.Therefore,it is necessary to carry out explosion proof design on the working circuit and structure of the instrument to meet the national mining product standards.In response to the special environment underground in coal mine,there are two aspects that need to be considered in the mechanical structure design,namely the requirements for strength and performance,and the design of the explosion proof joint surface of the instrument.The reliability will be verified through a combination of finite element simulation,force analysis,and experimental testing,providing reference for the development of electromagnetic wave logging while drilling direction instrument suitable for underground coal mine.
