1981年以来,我队先后在陆丰南告水利工程围幕灌浆孔、饶平溪西钼矿区、惠来鹅地金矿区和211矿区,使用自行设计的GY-54型液压冲击器.经过累计进尺1084.08米(最大孔深800米)、512.12台时、392回次的金刚石冲击回转钻进的情况来看,该冲击器设计合理,结构简单,操作容易,拆装、调整方便,工作性能稳定.在不增加附属设备的条件下,使用冲击回转钻进可提高钻进效率,保证工程质量.尤其在破碎地层中岩芯不易堵塞,增加回次进尺,减少辅助时间,
Since 1981, our team successively used the self-designed GY-54 hydraulic impactor in the Lufengnan Water Conservancy Project surrounding curtain grouting hole, Raopingxixi molybdenum mine area, Huilai goode gold mine area and 211 mining area. With a footage of 1084.08 meters (maximum hole depth of 800 meters) and 512.12 sets of 392 times of diamond impact rotary drilling, the impactor has a reasonable design, simple structure, easy operation, disassembly and assembly, convenient adjustment and stable working performance Without adding auxiliary equipment, the use of impact rotary drilling can improve the drilling efficiency and ensure the quality of the project.Especially in the broken strata in the core is not easy to block, increase back to the footage, reduce auxiliary time,
