XY-1A Core Drilling Rig Main Futures
1.When the final holes are respectively 75mm and 46mm in diameter, the rated hole depths are separately 100m and 180m. The maximum of depth my not exceed 110% of that drilled in each hole.The maximum allowable hole diameter is 150mm.
2.With hydraulic feeding device, elevated drilling efficiency, reduced labor strength.
3.The rig is equipped with an upper spherical jaw holding mechanism and hexagonal drive drilling rod which can be replaced without shutdown, high efficiency, safe and reliable.
4.A hole bottom pressure gauge is mounted indicating the pressure in order to control the staus inside the hole 5.Compact structure, small volume, lightweight, high detachablity, easy transportation and suitable for the operations in plains or mountain areas.
How is exploration drilling done?
Buckle the lifter into the groove of the variable diameter joint, move the right handle of the winch to take the pad fork, take out the perforated pipe, install the core tube, lift the drilling tool to the top of the borehole, move the left handle of the winch continuously, and lower the drilling tool into the borehole at a uniform speed. When the groove of the variable diameter joint is close to the inlet, use the pad fork to block and remove the lifter.
Drilling consists of sinking a drill string into the ground while injecting a special mud. This allows fragments of rock and samples of gas to be brought back to the surface. Boreholes have to be drilled at several locations to delineate the potential deposit.
