摘要
根据我国地质钻探任务不断增加和向地层深部找矿的需求,研制了XD-3型全液压动力头式岩心钻机。介绍了该钻机的结构设计、工作原理、主要特点以及使用情况。
According to the continuous increase of geological drilling job,and the demand for prospecting in deep zone,XD-3 all hydraulic top drive core drill was developed.The paper introduced the drill on structural design,operational principle,main features and its application.
