广东探矿工艺研究队设计研制、局探矿机械厂生产的GY-54型液动冲击器,用于金刚石冲击迴转钻进,已在六个队(九个矿区)试验和推广,投入冲击器十五套,据不完全统计,完成金刚石冲击迴转钻进工作量117444.62米,完工钻孔27个,平均小时效率比迴转钻进提高16%—112%,回次进尺增加12%—106%,完工钻孔质量全优,“打滑”地层钻进问题基本得到解决,获得了显著的技术经济效果。
GY-54 type hydraulic impactor produced by the Bureau of Prospecting Technology of Guangdong Province and designed and manufactured by Bureau of Exploration and Production Machinery has been tested and popularized in six teams (nine mining areas) According to incomplete statistics, the completion of diamond impact rotary drilling workload 117444.62 meters, completed 27 boreholes, the average hourly efficiency than rotary drilling increased by 16% -112%, back to the footage to increase by 12% -106% , The quality of completed drilling is all excellent, the drilling problem of “slippery” formation is basically solved, and significant technical and economic effects have been obtained.
