16. The hole opening workers are not allowed to hold their hands at the bottom of the cushion fork handle. The power of the upper and lower cushion forks should be cut off first. After the coarse diameter drilling tools are lifted out of the hole opening, they should hold the pipe body of the drilling tools with both hands. It is prohibited to put their hands into the drill bit to test the rock core or look down at the rock core with their eyes. It is not allowed to hold the bottom of the drilling tools with their hands.

18. When lifting and running the drill, the drilling rig operator shall pay attention to the height of the elevator, and can only put it down when the workers at the orifice are in a safe position. It is strictly prohibited to put the drilling tool down to the bottom.
19. When the winch is working, it is strictly forbidden to touch the wire rope with hands. The spacer fork cannot be started until it leaves the drilling tool.
20. When hammering, a special person shall be assigned to command. The lower drill pipe of the hammer must be equipped with an impact handle.
