摘　　要：液压系统是全液压钻机的核心,对整机性能影响很大。为了提高全液压钻机的性能,分析了国内全液压动力头式坑道钻机液压系统的现状,研究了负载敏感技术的节能、流量稳定、操控简便等特性,并将该技术应用在ZDY6000L型履带式全液压坑道钻机的回转回路上。结合钻探工艺及操作控制等方面分析该回转回路的节能、启动特性好以及保护钻头等优点,经型式试验和工业性试验表明,该技术完全满足钻机回转的性能要求,在全液压钻机的回转回路上有良好的应用前景。The hydraulic system is the key part of the hydraulic drilling rig and has a great importance to the performances of the drilling rig. In order to improve the performances of the hydraulic drilling rig, the paper analyzed the present hydraulic system status of the mine roadway hydraulic driving head drilling rigs in China and researched the energy saving, flow stability, operation easy and other features of the load sensitive technology. The sensitive technology has been applied to the hydraulic retuming way of the rotary part in the ZDY6000L caterpillar hydraulic drilling rig. In combined with the drilling technology and operation control, the paper analyzed the energy saving, good starting performance, drilling head protection and other advantages of the hydraulic returning way of the rotary part. The mode test and industrial test showed that the technology could fully meet the rotary performance requirements of the drilling rig. The technology has an excellent application prospect in the rotary hydraulic retuning way of the drilling rig.
