Using our C1000 drilling rig, we conducted the exploration for gold mines in Luoning County, Henan Province. With NQ drill rods, the final hole diameter was 71mm. The characteristics of the mining area project were a small construction angle, dense hole positions, and fractured strata. The minimum construction angle of our equipment was 28°, and the maximum hole depth was 450m. The maximum daily advance length reached over 100 meters.
