摘　　要：提高全液压坑道钻机液压系统的技术水平,对于改善钻机整机性能及提高瓦斯抽采孔的成孔率具有重要意义。在对全液压坑道钻机液压系统现状分析的基础上,根据钻探工艺和液压传动控制系统节能的要求,设计了ZDY6000L型覆带式全液压坑道钻机液压系统,其功能主要包括行走回路、回转回路、给进回路和辅助回路。经型式试验和现场工业性试验表明,该液压系统设计合理、先进可靠,具备良好的机动性,且节能增效。It is significant to improve the hydraulic system for better performance of drilling rig and the higher ratio of finishing gas hole. The current state of the development of hydraulic system drilling rig in tunnel is discussed from the perspective of the drilling process and energy saving. The hydraulic system of ZDY6000L track-mounted drilling rig is developed, and rotational, feeding and assistant loops are described. The experiment of ZDY6000L drilling rig showed that the developed hydraulic system is of high effectiveness and reliability, as well as fine flexibility and energy saving.
