为满足煤矿井下瓦斯长距离抽采孔及底板注浆孔和穿层孔等多种施工方案对钻机的新要求,在分析了国外钻机的不足的基础上,通过将整套设备分为钻车和泥浆泵车两部分的整体解决方案,设计了ZDY6000LD(B)履带式全液压定向钻机,钻车和泵车可独立行走,同时钻车主机可大角度调整倾角。现场应用表明,ZDY6000LD(B)履带式全液压定向钻机狭窄巷道的适用性强、操作便捷且钻进效率高,是一款多用途煤矿井下钻孔施工设备。
In order to meet the new requirements of drilling rigs for various drilling schemes such as long-distance gas drainage holes in underground coal mines and grouting holes and perforated holes on the floor, the paper analyzes the shortages of overseas rigs, divides the whole set of equipment into drilling vehicles and Mud pump truck two parts of the overall solution designed ZDY6000LD (B) crawler hydraulic steering drilling rigs, drilling and pump can walk independently, while the main drilling rig can be adjusted for large-angle tilt. The field application shows that the ZDY6000LD (B) crawler hydraulic steering drill has the advantages of narrow tunnel, convenient operation and high drilling efficiency. It is a multi-purpose coal mine underground drilling construction equipment.
