Abstract

The invention discloses an in-hole drilling tool integrating drilling, slotting and punching a coal seam and a using method thereof. The in-hole drilling tool comprises a water supple device or an air supple device, a high-pressure sealing drill pipe, a slotting and punching valve and a drill bit. The water supply device and the air supply device are connected with the high-pressure sealing drill pipe at an orifice. The slotting and punching valve is installed between the high-pressure sealing drill pipe and the drill bit. The in-hole drilling tool is essentially used for drilling and anti-reflective outburst eliminating after drilling of soft outburst coal seam. The using method is as follows: after the drilling construction is finished, a water supplier with a pressure release valve is used for starting a high-pressure pumping station to improve the pressure and the flux for water supply; high-pressure water current at the pumping station drives the slotting and punching valve to act for closing an axial liquid passage and opening a radial liquid passage; and high-pressure jet current realizes slotting or punching through a cutting nozzle or a punching nozzle. The invention has novel design and easy operation, is safe and reliable, improves the outburst elimination efficiency and realizes the integrated operation of drilling, slotting or punching and outburst eliminating.

Description

technical field [0001] The invention belongs to the technical field of drilling soft and outburst coal seams in coal mines and the technical field of anti-reflection and anti-burst after drilling, and in particular relates to an integration of coal seam drilling, slotting and punching for coal seam drilling, high-pressure hydraulic slotting or punching construction In-hole drilling tool and method of use thereof. Background technique [0002] For a long time, drilling and eliminating outbursts in outburst coal seams have been recognized both at home and abroad as difficult problems in gas control in outburst coal seams. The vast majority of outburst coal seams in my country are soft and soft outburst coal seams with relatively poor air permeability. Drilling coal seams and enhancing permeability and eliminating outbursts are one of the domestic research hotspots. At present, the commonly used slotting anti-reflection method is to drill a hole with sufficient depth, withdraw...
