[0002] When drilling with a drilling rig for deep hole blasting and gas extraction in coal mines, the azimuth angle of the drill hole is difficult to control. The azimuth angle of the drill rig is generally determined by the following method: use a theodolite to give points, mark two points on the top plate of the tunnel with red paint, and use a ruler to measure the same distance on the basis of the two red points when drilling to determine two more points, and then use the straight line determined by the two points to determine the direction. The inclination angle of the drill rig is generally determined by a semicircular instrument or a slope gauge. After the azimuth and inclination angles are determined, fix the drill rig and start drilling.
