近两年来，我们在某矿区一○三号机台使用云南地质技工学较实验站研制的射吸式54—3型冲击器进行了冲击回转钻进实验。试验完工9个钻孔，工作量1628.36米，平均台月效率为659米，最高单孔台效达到1926米。与普通双管回转钻进相比，钻进大理岩时的平均时效提高了31％，钻进坚硬的石英钾长交代岩和混合花岗岩时效提高了88％以上。完工钻孔六项质量指标均达到地质要求。试验中孔内事故和设备事故很少，分别为14.5％和1.7％。单位成本明显下降，取得了较好的钻进实验效果。现将钻进试验情况介绍如下。
In the past two years, we conducted impact-driven drilling experiments with a suction-type 54-3 impactor developed by Yunnan Geotechnical Engineering Laboratory at No.10 in a mining area. The test completed nine holes, the workload of 1628.36 meters, the average station efficiency of 659 meters, the highest single-hole Taiwan reached 1926 meters. Compared with the conventional two-pipe rotary drilling, the average aging time of drilling marble increased by 31%, and the hard aging of potash-bearing quartzite and mixed granite increased by more than 88%. Completion of drilling six quality indicators have reached the geological requirements. There were very few accident and equipment accidents in the test holes, accounting for 14.5% and 1.7% respectively. Unit costs decreased significantly, and achieved good drilling results. Drilling test conditions are introduced below.
