摘要: 煤矿井下智能化钻探技术装备是煤矿智能化建设的重要组成部分，也是当前煤矿企业深入推进减人增效工作所急需的先进技术装备。系统总结了“十三五”期间我国煤矿井下智能化钻探技术装备所取得的阶段性成果，重点介绍了自动化钻机、随钻参数监测系统和旋转导向系统等关键技术装备的发展现状。全面分析了制约井下智能化钻探技术装备研发与应用的关键因素：钻机智能化水平较低、随钻探测数据类型少、多系统集成控制难。在此基础上提出深入推进数字化、网络化、智能化技术与传统坑道钻探技术结合，强化多学科融合和协同创新能力；并不断加强智能化钻探技术装备研发与应用人才的培养力度，以技术装备为支撑、以数字化平台为保障、以人才队伍建设为基础；在智能化钻机、高精度数据获取与传输技术、钻孔轨迹智能优化与控制技术、辅助关联设备集成控制技术、数字化钻进平台开展攻关，以实现煤矿井下钻孔全流程智能化施工作业。Abstract: The intelligent drilling technology and equipment are important part of the intelligent construction of coal mine, and it is the advanced technology and equipment urgently needed by coal mine enterprises to further promote the work of reducing personnel and increasing efficiency. The phased achievements of underground intelligent drilling technology and equipment during the 13th five-year plan are systematically summarized, and the development status of key technical equipment such as automatic drilling rig, parameter monitoring of measurement while drilling(MWD) system, rotary steerable system are introduced. The key factors restricting the research and development (R & D) and application of intelligent drilling technology and equipment are comprehensively analyzed: low level of drilling rig intelligent, few types of MWD data, and difficulty in integrating and controlling multi systems. On this basis, it is proposed to deeply promote the combination of digital, networked and intelligent technologies with traditional pit drilling technologies, strengthen multidisciplinary integration and collaborative innovation capabilities, and continuously strengthen the cultivation of intelligent drilling technology and equipment research and application talents. With technical equipment as the support, digital platform as the guarantee, and talent team construction as the basis, the problems will be tackled in the following aspects: the intelligent drilling rig, the technology of high-precision data acquisition and transmission, the technology of intelligent optimization and control of trajectory, the technology of integrated control of auxiliary related equipment, the digital drilling platform, and the underground intelligent drilling in the whole process of coal mines will be realized.
