摘要
近水平定向长钻孔钻进技术是提高我国煤矿井下瓦斯抽采效率的一条重要途径。介绍了ZDY6000LD(A)型履带式全液压千米定向钻机的研制,包括整体布局、履带底盘、主要结构和液压系统。井下试验表明,该钻机适于在井下巷道钻进孔深1 000 m以上的多分支钻孔,性能可靠,定向精度高,移动稳固、快速、方便。
Sub horizontal long hole drilling technique is an important approach to improve the efficiency of gas drainage and ensure safe mining in underground coal mines.Drilling rig is the main drilling equipment to realize the pivotal technique.The development of the track-mounted ZDY6000LD（A） hydraulic directional drilling rig is introduced in this article,including the position,track-mounted,main structure and hydraulic system.Underground test proved that the rig is suitable to drill branched boreholes of more than 1000 m,reliable in performance,high in precision,stable,fast and convenient in movement.
