Abstract

The invention relates to a drill pipe water supply device. The drill pipe water supply device comprises a water supply mechanism, a water supply connector and a drill pipe; the drill pipe is connected to an outlet of the water supply mechanism through the water supply connector. By means of the drill pipe water supply device, the performance of a whole system is improved by improving components in the whole structure, and technical problems caused by the specific components are solved.

Description

technical field [0001] The invention relates to a hole reaming auxiliary device, in particular to a drill pipe water supply device. Background technique [0002] According to the mine gas control plan, the gas concentration in the borehole often fails to achieve the expected effect by using the existing gas drainage measures, mainly because the coal seam has poor air permeability. Through experimental research, the construction essentials of hydraulic punching, hydraulic punching And its anti-burst mechanism, studies have shown that the use of floor rock roadway through-layer drilling and hydraulic punching area anti-burst measures can effectively eliminate outburst stress, greatly increase the air permeability of the coal seam, and ensure safe and efficient mining of the working face. [0003] When adopting hydraulic punching, it is necessary to constantly replace the drill pipe bit, because at the beginning, the drill bit is used to drill the hole with low-pressure water, ...
