矿山装备多运行在重载、潮湿、隔爆等极端工况环境下，传统的矿山装备驱动系统通常采用交流异步电机驱动技术,为实现矿山的连续化生产，设备经常运行在低效工作区间，智能化程度低，存在着严重的电能浪费。随着电力电子技术与现代电气传动控制技术的发展，永磁驱动技术作为一种利用高效永磁同步电机驱动负载的绿色智能化驱动技术，已经在电动汽车、轨道运输与自动化生产等多个领域得到了应用，但目前在矿山装备领域的应用相对较少，具有广阔发展前景。首先，通过与传统的交流与直流电机对比，介绍了永磁驱动最常用的3种电机:永磁同步电机、永磁无刷直流电机、永磁直线电机的结构特点及应用现状；其次，根据矿山装备运行工况特点，对永磁电机常用的3种变频调速技术进行了分析比较，突出了永磁驱动技术应用于矿山装备领域的优越性。在此基础上，着重分析了永磁驱动技术在矿山采掘装备、矿井运输装备、矿井提升装备上的应用和研究现状，指出针对采掘装备截割部与刮板输送机所处的重载、突变负载等需要低转速大转矩运行的工况，可发展永磁半直驱系统；针对带式输送机所处重载工况和输送带摩擦传动特点，可应用“永磁直驱+永磁张紧”的全永磁智能型驱动系统；为适应超深矿井提升载荷和提升深度的不断增加，可发展“钢丝绳+永磁直线电机”复合驱动的新型矿井提升系统。最后，对矿山装备领域永磁驱动技术的研究重点与发展方向进行了展望，认为面向矿山极端工况大力发展高可靠性永磁驱动技术、基于高效永磁驱动技术开发智能化矿山装备是该领域未来的主要发展方向。

Mining equipments are mostly operated in extreme environments with heavy load, humidity and explosion-proof conditions. The traditional driving system of mining equipment usually adopts the AC asynchronous motor drive technology, the equipment often runs in the low efficiency working area for the continuous production of the mine, so the degree of intelligence is low, and there is serious power waste. With the development of power electronic technology and modern electric drive control technology, permanent magnet driving technology, as a kind of green intelligent driving technology which uses permanent magnet motors to drive load, has been applied in many fields such as electric vehicle, rail transportation and automatic production, but it is less used in the field of mining equipment and has a broad development prospect. Firstly, compared with the traditional AC and DC motors, the three most commonly used permanent magnet motors for permanent magnet drive are introduced:permanent magnet synchronous motor, permanent magnet brushless DC motor, permanent magnet linear motor. At the same time, according to the characteristics of mining equipment operation conditions, the paper analyzes and compares three common frequency control technologies used in permanent magnet motor, and the advantages of permanent magnet drive technology in the field of mining equipment are highlighted. On this basis, the application and research status of permanent magnet driving technology in mining and tunneling equipment, mine transportation and hoisting of mine are analyzed, it is pointed out that:in order to further promote the application of permanent magnet driving technology in the field of mining equipment, the permanent magnet semi-direct drive system can be developed for the heavy load, sudden load and other operating conditions requiring low speed and high torque operation condition of the cutting part of mining equipment and scraper conveyor; the permanent magnet semi-direct driving system should be vigorously developed; With the characteristics of heavy load friction transmission, the full permanent magnet intelligent driving system of“permanent magnet direct drive+permanent magnet tension” can be applied; in order to adapt to the increasing load and lifting depth of the ultra-deep well, the new type of mine hoisting system driven by “wire rope + permanent magnet linear motor”is developed. Finally, the research focus and development direction of permanent magnet driving technology in the field of mining equipment are prospected. It is considered vigorously developing high-reliability permanent magnet driving technology for extreme mining conditions and developing intelligent mining equipment based on permanent magnet driving technology should be main development direction of this field.
