Description

Technical Field

[0001] This invention relates to an anti-outburst drilling rig device and its usage method, particularly an anti-outburst drilling rig device and its usage method for use in coal mine roadways. Background Technology

[0002] With increasing coal mining depth, gas accidents are on the rise, posing a serious threat to coal mine safety and personnel safety. Gas control has become a top priority in coal mining. The emission of gas from coal seams in high-outburst working faces is crucial to improving safety and efficiency. Outburst-prevention drilling rigs are commonly used in coal mines with high outburst faces. Therefore, outburst-prevention drilling rigs used in coal mine roadways are an important type of coal mine equipment. However, existing outburst-prevention drilling rigs used in coal mine roadways are mostly column-mounted, double-hydraulic outburst-prevention drilling rigs. Because they use a portal frame support and dual hydraulic motors for power, there is no correlation between the working state of the drill rod and the gas concentration signal, thus affecting the safety performance of the outburst-prevention drilling rig.

[0003] This invention, through its technical feature of establishing a correlation between the working state of the drill rod and the gas concentration signal, effectively explores and studies the technical problems of dual-split hydraulic anti-outburst drilling rigs at the technical level.

[0035] This invention designs a method for using an anti-outburst drilling rig in coal mine roadways. The steps are as follows: the drilling rig body enables drilling operations on the coal seam of the high-outburst working face; the sleeve device generates an external braking force on the drill rod; and the control signal device uses the gas concentration signal as the control basis signal to achieve a correlated control state between the working state of the drill rod and the gas concentration signal.

[0036] The technical effect of the above technical solution is that it highlights the technical feature of making the working state of the drill rod and the gas concentration signal in a correlated control state, and introduces its application in the technical field of the use of anti-outburst drilling equipment in coal mine roadways.

[0037] The present invention comprises the following steps: When drilling operations are required in a high-outburst coal seam, the power unit is put into operation, high-pressure fluid is input to the operating platform, and the chassis is moved through the operating platform. The mobile drilling rig chassis is positioned at the drilling position in the high-outburst coal seam, the outriggers I and II are extended, and the chassis is lifted off the ground. The drill rod is placed in the chuck and clamp, and the rotating tube, box, brush, and cylinder are fitted onto the drill bit. The lateral angle of the drill rod is adjusted in all directions through the rotary support. The height of the drill rod is adjusted by moving the movable seat on the guide column through the lifting telescopic cylinder. The height of the drill rod is adjusted by rotating the motor on the movable seat. The upper part rotates, causing the slide to swing, thus adjusting the up-and-down swing angle of the drill rod. This places the drill bit on the drilling point located in the coal seam of the high-protrusion working face, putting the chuck in working condition and driving the drill rod to rotate. This connects the outer end of the gas pipeline section to the outer end of the shell section I, connecting pipeline section I to the high-pressure gas source and pipeline section II to the high-pressure flocculant mixed liquid source. The gas-liquid mixed medium is sprayed into the mixing cavity through the nozzle section, creating a vacuum in the mixing cavity. This puts the starter section in working condition, as well as the electric valve controller section, power controller section, and gas sensor section in working condition. The electric valve section is in the off state, and the gas bladder section is in a non-inflated state. The three arc-shaped plates of the rotating tube are separated, separating the rotating tube from the drill rod. The drill rod rotates within the rotating tube, box, brush, and cylinder sections, extending the propulsion cylinder of the slide section. This allows the drill rod to drill into the coal seam of the high-protrusion working face. Under the action of the mixing cavity, the gas and dust generated during drilling enter the box section through the cylinder section, and then are injected into the mixing cavity through the gas delivery pipe. In the mixing cavity, the gas and dust generated during drilling are fused with the gas-liquid mixing medium to obtain a fused gas-liquid mixture. This fused gas-liquid mixture is discharged into the dust collector section through the shell section II. In the dust collector section, solid-liquid centrifugal treatment is performed, and the dust is discharged through the lower port of the dust collector section. Clean gas is released through the upper port of the dust collector and detected by the gas sensor on the coal seam in the high-outburst working face. When the gas concentration detected by the gas sensor exceeds a specified value, the gas sensor sends a signal to the power controller, activating it and de-energizing the electric valve controller. The electric valve controller then activates, opening the valve and injecting high-pressure gas from the high-pressure gas source into the gas chamber, causing it to inflate. This inflates the gas chamber and closes the three arc-shaped plates of the rotating tube, which then acts on the drill rod, externally braking it and stopping drilling operations in the coal seam of the high-outburst working face.To reduce the high concentration of methane in the coal seam of a high-outburst working face, the starter unit is activated when the methane concentration signal detected by the methane sensor is lower than the specified methane concentration value. After drilling is completed in the coal seam of the high-outburst working face, the starter unit is deactivated, the slide block's propulsion cylinder is retracted, the rotating pipe section, box section, brush section, and cylinder section are removed from the drill bit, the drill rod is removed from the chuck and clamp section, the outer end of the gas pipeline section is separated from the outer end of the cylinder section I, the pipeline section I is disconnected from the high-pressure gas source, the pipeline section II is disconnected from the high-pressure flocculant mixture source, the outriggers I and II are retracted, the chassis is placed on the ground, and the chassis is put into motion. The mobile drilling rig chassis is then positioned at the drilling position of the next high-outburst working face coal seam.

[0038] The technical effect of the above solution is that it enables drilling operations in a safe state on coal seams in high-outburst working faces, thus meeting the needs of drilling on coal seams in high-outburst working faces.

[0039] In this technical solution, the drilling rig body, sleeve device, and control signal device are basic components and essential technical features of the invention. The mobile drilling rig chassis, dust collection device, and bracket are functional components that enable other technical effects of the invention.

[0040] In this technical solution, the correlation between the working state of the drill pipe and the gas concentration signal is achieved by the sleeve device and the control signal device.

[0041] In this technical solution, the drilling rig body, sleeve device, and control signal device that establish a correlation control between the working state of the drill rod and the gas concentration signal are important technical features.

[0073] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0074] A method for using an anti-outburst drilling rig in a coal mine roadway includes the following steps: When drilling is required in a coal seam with a high outburst working face, the power unit 13 is put into operation, high-pressure fluid is input to the operating platform 14, and the chassis 11 is put into motion through the operating platform 14. The mobile drilling rig chassis 1 is positioned at the drilling position in the coal seam with the high outburst working face, the outriggers I 15 and II 16 are extended, the chassis 11 is lifted off the ground, the drill rod is placed in the chuck 61 and the clamping device 63, and the rotating tube 23, the box 21, the brush 25, and the cylinder 26 are fitted onto the drill bit of the drill rod.

[0075] The rotary support 17 enables omnidirectional lateral angle adjustment of the drill rod. The lifting telescopic cylinder 19 moves the movable seat 10 on the guide column 18, allowing for height adjustment of the drill rod. The rotating motor 64 rotates on the movable seat 10, causing the slide 62 to swing, thus adjusting the vertical swing angle of the drill rod. This allows the drill bit to be positioned at the drilling point in the high-protrusion coal seam.

[0076] The chuck section 61 is put into operation, driving the drill rod to rotate. The outer end of the gas delivery pipe section 24 is connected to the outer end of the shell section I 31. Pipe section I 36 is connected to the high-pressure gas source, and pipe section II 38 is connected to the high-pressure flocculant mixed liquid source. The gas-liquid mixed medium is sprayed into the mixing cavity 301 through the nozzle section 35, creating a vacuum in the mixing cavity 301. The starter section 45 is put into operation, as are the electric valve controller section 42, the power controller section 43, and the gas sensor section 44. The electric valve section 41 is in the off state, the air bladder section 22 is in a non-expanded state, and the three arc-shaped plates of the rotating tube section 23 are separated, separating the rotating tube section 23 from the drill rod. The drill rod rotates... The rotating section 23, box section 21, brush section 25, and cylinder section 26 rotate, causing the propulsion cylinder of the slide section 62 to be in an extended state, enabling the drill rod to perform drilling operations on the coal seam of the high-protrusion working face. Under the action of the mixing inner cavity 301, the gas and dust generated during the drilling operation enter the box section 21 through the cylinder section 26, and then are injected into the mixing inner cavity 301 through the gas delivery pipe section 24. In the mixing inner cavity 301, the gas and dust generated during the drilling operation are fused with the gas-liquid mixing medium to obtain a fused gas-liquid mixture. The fused gas-liquid mixture is discharged into the dust collector section 34 through the shell section II 32. In the dust collector section 34, solid-liquid centrifugal treatment is performed. The dust is discharged through the lower port of the dust collector section 34, and the clean gas containing gas is released through the upper port of the dust collector section 34.

[0077] The gas sensor unit 44 picks up the gas concentration signal on the coal seam of the high-outburst working face. When the gas concentration signal picked up by the gas sensor unit 44 is greater than the specified gas concentration value, the gas sensor unit 44 inputs a signal to the power controller unit 43, causing the power controller unit 43 to be in working state, the electric valve controller unit 42 to be de-energized, and inputs a signal to the electric valve unit 41, causing the electric valve unit 41 to be in open state. Through the valve unit 41, high-pressure gas from the high-pressure gas source is injected into the airbag unit 22, causing the airbag unit 22 to be in an inflated state. This causes the three arc-shaped plates of the rotating tube unit 23 to be in a closed state, causing the rotating tube unit 23 to act on the drill rod, putting the drill rod in an external braking state, stopping the drilling operation on the coal seam of the high-outburst working face, and reducing the high concentration of gas on the coal seam of the high-outburst working face. When the gas sensor unit 44 picks up the gas concentration signal on the coal seam of the high-outburst working face less than the specified gas concentration value, the starter unit 45 is then put into working state.

[0078] After completing the drilling operation on the coal seam of the high-outburst working face, the starter unit 45 is put into a non-working state, the propulsion cylinder of the slide unit 62 is put into a retracted state, the rotating tube unit 23, the box unit 21, the brush unit 25 and the cylinder unit 26 are removed from the drill bit of the drill rod, the drill rod is removed from the chuck unit 61 and the clamping unit 63, the outer end of the gas transmission pipe unit 24 is separated from the outer end of the cylinder shell unit I 31, the pipe unit I 36 is disconnected from the high-pressure gas source, the pipe unit II 38 is disconnected from the high-pressure flocculant mixed liquid source, the outrigger unit I 15 and the outrigger II 16 are put into a retracted state, the chassis unit 11 is placed on the ground, the chassis unit 11 is put into a moving state, and the mobile drilling rig chassis 1 is placed in the drilling position of the next high-outburst working face coal seam.

[0079] In verifying this invention, the inventors abandoned the existing technical features of column-mounted double-split hydraulic anti-outburst drilling rigs and first proposed a technical feature that links the working state of the drill rod with the gas concentration signal, resulting in the first unexpected technical effect: achieving the condition of setting the necessary gas concentration signal value for drilling operations in high-outburst coal seams; the second unexpected technical effect: achieving dust removal treatment of the construction environment in high-outburst coal seams, ensuring the cleanliness of the construction environment; and the third unexpected technical effect: the rotating motor unit 64 enables high-outburst drilling on steep slopes. The drilling operation on the coal seam yielded the fourth unexpected technical effect: it enabled a large-scale adjustment of the drill rod position. The fifth unexpected technical effect: it eliminated the generation of gas dust, thus reducing the risk of explosion. The sixth unexpected technical effect: the movable drilling rig chassis 1 provided stable support for the drilling rig body 6, preventing impact on the rotating drill rod and extending its service life. The seventh unexpected technical effect: it ensured the rotating drill rod remained stable, improving the size and positional accuracy of the borehole.

[0080] In a second embodiment of the present invention, the drilling rig body 6, the sleeve device 2, and the control signal device 4 are interconnected in a manner that establishes a correlation between the working state of the drill rod and the gas concentration signal.

[0081] In this embodiment, the control signal device 4 is connected to the drilling rig body 6 and the sleeve device 2 in a manner that uses the gas concentration signal as the control basis signal.

[0082] In this embodiment, a first attachment device is also included and is disposed on the drilling rig body 6. The first attachment device is configured as a mobile drilling rig chassis 1.

[0083] In this embodiment, a second accessory device is also included and is disposed on the sleeve device 2. The second accessory device is configured as a dust collection device 3.

[0084] In this embodiment, a third accessory device is also included and is disposed between the control signal device 4 and the first accessory device. The third accessory device is configured as a bracket 5.

[0085] The second embodiment of the present invention is based on the first embodiment.

[0086] In the second embodiment of the present invention, the steps are as follows: the drilling rig body 6 realizes drilling operations on the coal seam of the high-burst working face; the sleeve device 2 realizes the external braking force on the drill rod; and the control signal device 4 realizes the working state of the drill rod and the gas concentration signal are in a correlated control state, with the gas concentration signal as the control basis signal.

External braking force is generated on the drill rod through the sleeve device 2. The control signal device 4 realizes the correlation between the working state of the drill rod and the gas concentration signal by using the gas concentration signal as the control basis signal. This solves the technical problems of the double-split hydraulic anti-outburst drilling rig with column support, thus improving the safety performance of the anti-outburst drilling rig device.

[0090] 2. Due to the design of the mobile drilling rig chassis 1, the drilling rig body 6 and the bracket 5 are provided with motion support.

[0091] 3. Due to the design of dust collection device 3, the gas and dust generated during drilling operations can be purified.

[0092] 4. Due to the design of bracket 5, the control signal device 4 is supported as the drilling rig chassis 1 moves.

[0093] 5. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.
