Drilling Technology

1. Move the drill rig to the drilling location, adjust the angle to 10 degrees, and extend the leg to touch the ground (try to get both tracks and legs in contact), align with the drilling location;

2. First install a drill pipe, then attach the drill bit, place a wooden board at the mouth of the hole, start up the main machine. Use a gripper to position the drill pipe, rotate it with compressed air until it reaches the correct position, pay attention to the speed while drilling and observe the sedimentation situation;

3. Continuously operate the drill pipe to reach the required depth, pay attention to the side cleaning of the hole, do not wait until the end to clear out the sediment; 

4. Remove the drill pipe;

5. Withdraw the leg and move the drill rig to the next drilling location.
