The YDX-3L type core drill with hydraulic power head type developed by the Tianhebang exploration technology Co.,Ltd., in Beijing and ministry of land and resources exploration technology research institute,was suitable for diamond rope core and various other effective drilling process methods.Taking the borehole ZK0005 of the Baoxinggou orefield as an example,we introduced performance parameters of the YDX-3L drill,and focused on analyzing the drill in deep hole drilling process drilling pressure,rotating speed and reasonable selection of pump according to the geological conditions of mining area and the drilling design requirements.Additionally,some deficiencies during the process of drilling rig construction work were given,and we put forward some improvement suggestions and solutions so as to exert its maximum benefits in different mining applications.
