Background
In the coal mining process, drilling holes need to be constructed in time for coal detection, water detection, geological structure detection, gas extraction and the like, a large amount of rock dust and coal dust are generated in both rock drilling construction and coal seam drilling construction, the dust is easily absorbed into the lung by workers through breathing, pneumoconiosis is caused seriously, and the health of the workers is threatened seriously. Meanwhile, dust easily pollutes a working site, dust on the construction site is diffused, the sight of workers is blocked, hidden dangers are buried for various accidents, and safety production is not facilitated. Although the dust can be discharged through ventilation in the drilling construction process, the generation of dust cannot be fundamentally solved, and the condition that the dust harms workers still exists.

The outer channel of the drill rod is cylindrical with the diameter of 5 mm.
Three outer channels are symmetrically distributed in the drill rod.
The diameter of the nozzle is 2mm, and the inclination angle of the nozzle is 30 degrees.
Three groups of nozzles are uniformly distributed on the drill rod, and three nozzles are symmetrically distributed on each group of nozzles.
The conical nozzle is conical and 10mm in height.
The drill rod is a triangular drill rod.
The working principle of the invention is as follows: a spray dust-settling drill rod and a method thereof are disclosed, wherein drill rods are connected one by one, a tapered nozzle processed on the drill rod is inserted into an outer channel on the previous drill rod and is sealed by an O-shaped sealing ring, so that the sealing performance of the drill rods during connection is ensured; the outer channel of the drill rod is connected with a water supply system in the well during drilling, the inner channel of the drill rod is connected with a compressed air system in the well, compressed air of the inner channel is used for discharging slag, a drill bit is cooled, water in the outer channel is sprayed out through a nozzle, dust in the drilling process is reduced, and meanwhile, slag discharging can be accelerated, so that the purpose of eliminating the dust in the drilling hole is achieved.
After the technical scheme is adopted, the invention has the beneficial effects that: the spraying dust-settling drill rod and the method thereof solve the problems that the field dust is large during drilling construction, and the field dust is not beneficial to the health and safe production of workers, eliminate the dust generated during drilling by spraying water in the drill hole through the drill rod, greatly reduce the harm of the dust during drilling construction, and have the advantages of simple structure, good dust-settling effect and convenient popularization and application.
