The development of the LWD-200B full hydraulic open cut mine drill
In order to improve the technical level, perforation efficiency and ability of LWD-200B full hydraulic open cut mine drill to adapt to the complex geological conditions, we developed LWD-200B multi-function full hydraulic open cut mine drill, the drill has rotary cutting, impact and roller bit drill three functions.The drill travel use hydraulic motor to drive crawler belt running gear, low speed high torque hydraulic motor to direct top drive drilling rod.Pressure and lifting system use a long stroke hydraulic cylinder, wire rope and pulley mechanism, load sensing constant power variable pump, load sensing electromagnetic proportional multi-way directional valve.The control system uses electronic control handle and PLC controller, design pressure, speed, length, temperature sensors etc.and GPS base station, with real-time data acquisition, display, lithology automatic identification, closed-loop feedback control, GPS precise positioning, the manual and automatic drilling, specified depth or level drilling function.It applies to drilling diameter 150mm ~200mm blast hole in various types of open pit mine.
