The drill rig drilling system comprises a helical drill bit 3, a drill rod 4 and a drill rig 6. The auger bit 3 is mounted at the head end of the drill rod 4. The outer wall of the auger bit 3 is provided with helical blades 301. The auger bit 3 has an axial flow passage 304 therein. The top end of the spiral drill bit 3 is provided with a high-pressure nozzle 302 for injecting high-pressure water. The auger bit 3 communicates with the axial flow passage 304. The drill 6 grips the tail end of the drill rod 4. The drill rod 4 is a double-walled drill rod. The inner cavity of the inner pipe of the drill rod 4 is a central pore canal. And the wall surface of the inner pipe is provided with a flow guide through hole and a slag guide through hole. The annular space between the inner pipe and the outer pipe of the drill rod 4 is an annular hole. In which a support sleeve 401 is arranged. The surface of the support sleeve 401 is provided with support claws 4011 at intervals. The supporting hook 4011 is in a pressure spring structure.

In operation, the drill 6 drives the drill rod 4 to rotate and drill into the coal seam. The auger bit 3 is rotated from the shaft by the rotation of the drill rod 4. The nanofluid is fed into the auger bit 3 by means of a pressurizing pump 10. The high pressure jets 302 spray an axial high pressure stream of liquid to cut pilot holes in the coal walls at the bottom of the hole. The auger bit 3 enlarges the pilot hole. The coal rock mass is crushed by grinding with the auger bit 3 or by being subjected to high pressure water impact. The high-pressure water jet impacts the coal rock fragments, and the nano fluid carries the coal rock slag to return to the gas-slag separator main body 7.
In the embodiment, the water-based silicon dioxide nanofluid is injected into the drill hole through the drill bit nozzle, and meanwhile, the effect of stable internal pressure of the drill hole in the long-distance drilling process is achieved by adjusting the pressure maintaining pipe valve and the liquid injection pressure, so that the problems of spraying holes, hole collapse and the like in the long-distance drilling process are solved, and the safe and efficient exploitation of deep coal resources is guaranteed.
