Technical Field
The invention belongs to the technical field of mining, and particularly relates to a roller-bit drill hole cleaning device and a using method thereof.
Background
The rotary drill for the surface mine is mainly used for drilling blast holes in the surface mine and can also be used for surface drilling operation in earthwork engineering such as buildings, water conservancy projects, highways, railways, ports and the like. The principle is that the alloy teeth of the roller bit are intruded into rock by utilizing axial pressure, the bit is driven to rotate and roll during rotation, the alloy teeth roll, strip and cut the rock, and then the rock is crushed to form rock holes. Rock slag generated after rock crushing is powdered or fine particles, compressed air is sent to the bottom of a hole through the center of a drill rod by an air compressor and is blown out of a roller bit, and the rotary head drives the drill rod and the roller bit to rotate, so that the compressed air sweeps the bottom of the hole stripped of the rock slag through air holes of the drill bit. Blowing the blown rock slag and powder out of the formed hole along the gap between the drill rod and the hole wall of the formed hole through compressed air.
Rock slag powder blown out of the formed hole by the open-air roller drill falls back around the formed hole, and the rock slag powder accumulated at the hole opening is increased along with the increase of the drilling depth, so that an unstable rock slag pile is formed around the hole opening. After the drilling hole of the roller-bit drill reaches the designed depth, the roller-bit drill is lifted and removed, and workers are required to hook off rock slag at the hole opening by using a hoe, so that unstable rock slag is prevented from falling back into the hole and failing to reach the designed hole-forming depth, and the charging and blasting are influenced. Usually, 1 and 2 cubic meters of rock slag are formed at the periphery of each formed hole, and the workload and labor intensity for manually cleaning an unstable rock slag pile are large.
