1 rig safety rules, before the next drill rig to check whether the channel soft ground treatment works well, depth and rock drilling must be clearly the case, you must check the next diamond drill wear, the drill pipe for blockages, drill Knot whether injury. 2, drill, at least three people with one person operating the rig, plus one rod, one grasp opening, avoiding falling into holes drilled hole fast.
