用法和例句
Based on the drilling effects of 75 mm wire-line coring drilling by CS14 fully hydraulic driving head drill in Kangbao copper mine and polymetallic ore in Mongolia,the paper made the analysis on the advantages and disadvantages compared with spindle drilling machine and put forward the opinion that driving head drill was the trend in developing geological coring drill in China.
通过CS14型全液压动力头钻机在河北康保铜矿、内蒙古黄旗多金属矿2个矿区进行Φ75 mm绳索取心钻探效果,分析了全液压动力头钻机相对于立轴式钻机的优点及其不足,提出动力头钻机应是我国地质岩心钻机大力发展的趋向的看法。
The conic extruding bit usually be put into use when adopting percussionrotaryextruding drilling method to drill.
在冲击回转挤压成孔的钻进中通常采用圆锥型的挤压钻头，这种钻头在松软地层中的钻进效率很高，但在高围压下的中、硬塑性地层中的钻进效率明显降低。
