Several common drilling machine: Impact drilling machine with rope to the impact of the new drill wells to drilling machines, percussion mechanism driven by the power plant and drive up and down the rope and impact drill, chisel and crushed rock drilling. This is an ancient method of drilling equipment is simple, low cost, but drilling and fishing ballast must alternately, so slow drilling speed. Rotary drilling machine is powered by a turntable, drill pipe and drill together to drive rotary cutting, grinding and drilling geotechnical borehole with the drill continues to lengthen and deepen, with the circulating mud cuttings brought to the ground. It is faster than the speed of impact drilling machine drilling, and ease of handling the situation well collapse. Composite drilling machine is connected to the drill plus a red rotary drilling, the use of circulating liquid or gas rotary drill punch push the new spindle drilling machine equipment, while the impact of the drill and rotary crushing rock and drill two actions enter. Work drilling machine is pumping reverse circulation type. Its working principle is: the role of atmospheric pressure, circulating liquid by sedimentation through ring back to the ditch along the bottom of the wellbore flow gap, then the turntable drive drill, drill driven rotary drilling conducted by the mud pump The negative pressure suction debris build mud suction lumen of the new drill drilling machine picture, then rose to the faucet, the mud pump into the sedimentation tank, circulating fluid after precipitation continue to flow into the wellbore, again and again, to form an anti- circulation drilling work.
