[0002] The coal mining operation environment is complex and changeable, and accidents such as gas and coal dust explosion in the coal mining face threaten the life safety of underground workers and the normal operation of equipment at any time. In the safety protection system of the underground coal mine, the automatic explosion-proof device plays a key role as a "firewall". It can start quickly in the moment of gas or coal dust explosion, form an explosion-proof area, effectively block the further spread of explosion, control the harm in the smallest range, and gain valuable time for underground personnel evacuation and accident rescue, which is a solid defense line to ensure the safety production of coal mines.
[0003] When in use, the automatic explosion-proof device needs to be suspended on the roof of the crossheading on both sides of the coal mining face by using anchor rods, and needs to be set at a distance of 60-200 m from the coal mining face. With the continuous mining (forward advance) of the coal mining face, the automatic explosion-proof device also needs to move forward continuously. However, since the coal mining face will advance several meters every day, anchor rods need to be continuously constructed to move and fix the automatic explosion-proof device, which consumes a large amount of manpower and material resources and is low in efficiency. In addition, since the automatic explosion-proof device needs to be fixed on the roof of the crossheading, the operation personnel need to go up and down the ladder frame for disassembly and installation operation, which not only has high labor intensity, but also faces many safety risks such as falling from a high place and being injured by falling stones.

[0053] Example 2
[0054] Based on Embodiment 1, an automatic explosion-proof door-type following mobile device for use in underground coal mines, such as Figures 4-6 As shown in Embodiment 2 of the present invention, an automatic explosion-proof method for coal mining faces is also proposed, comprising the following steps:
[0055] S1: The coal mining face is set up and ready for mining; in the roadways 9 on both sides of the coal mining face, at a first set distance from the coal mining face, such as 200m away from the coal mining face, an automatic explosion-proof door-type moving device is set up.
[0056] S2: As Figures 4-5 As shown, the automatic explosion-proof door-type following mobile device is leveled; then, the hydraulic pump station 6 controls the support hydraulic cylinder 22 to extend and push the support pad 23 to support the two side walls of the roadway 9, thus fixing the automatic explosion-proof door-type following mobile device to the roadway 9 as a whole, and retracting the hydraulic telescopic support leg 24 to reduce the impact of the hydraulic telescopic support leg 24, support rod 25, scissor structure 26, and traveling wheel 27 on the normal passage of personnel and materials and the normal operation of equipment in the roadway 9;
[0057] S3: AsFigure 4 As shown, coal mining operations are being carried out at the coal mining face. When an accident such as a gas or coal dust explosion occurs at the coal mining face, the shock wave generated by the explosion triggers the automatic explosion-proof device 1 to work. The ultra-fine dry powder storage bin 15 sprays out atomized dry powder to form an explosion-proof zone, effectively preventing the further spread of the explosion.
[0058] S4: When the coal mining face is mined one or two steps at a time, or once a day, the position of the automatic explosion-proof door-type following moving device is adjusted once; specifically, the hydraulic retractable support leg 24 is extended by the hydraulic pump station 6 until the traveling wheel 27 touches the bottom, and the support hydraulic cylinder 22 is retracted by the hydraulic pump station 6 to release the automatic explosion-proof door-type following moving device from the roadway 9; the automatic explosion-proof door-type following moving device is moved to the first set distance from the coal mining face;
[0059] S5: Repeat steps S2-S4 until the entire working face is finished.
[0060] As a preferred embodiment of the second embodiment, in step S2, the flatness of the automatic explosion-proof door-type following moving device is determined and leveled based on the mining gyroscope 4 installed on the support panel 21.
[0061] As a preferred embodiment of the second embodiment, the ground monitoring system 7 acquires the working status of the automatic explosion-proof door-type moving device. When the automatic explosion-proof door-type moving device encounters special circumstances (such as falling or tilting), it can notify the relevant underground operators from the ground.
[0062] As a preferred embodiment of the second embodiment, in step S2, when the automatic explosion-proof door-type following moving device moves to a first set distance from the coal mining face and is unbalanced, it is balanced by placing pads under the traveling wheel 27 or the support rod 25, or by supporting it with hydraulic jacks; or, when the traveling wheel 27 is connected to the support rod 25 by two electric telescopic rods, with the two electric telescopic rods respectively set on the left and right sides of the traveling wheel 27, the top of which is connected to the support rod 25 and the bottom of which is connected to the central rotating shaft of the traveling wheel, the leveling is performed by telescopic electric telescopic rods.
[0063] As a preferred embodiment of the second embodiment, it also includes a shock wave detection sensor 10; in step S2; in the roadways 9 on both sides of the coal mining face, at a second predetermined distance from the coal mining face, for example, at a distance of 20m from the coal mining face, a shock wave detection sensor 10 is respectively arranged; the shock wave detection sensor 10 is communicatively connected to the hydraulic pump station 6; in step S3; when a gas or coal dust explosion or other accident occurs at the coal mining face, the shock wave generated by the explosion is detected by the shock wave detection sensor 10, the shock wave detection sensor 10 sends an emergency signal, and the hydraulic pump station 6 automatically controls the hydraulic retractable support leg 24 to quickly extend to the bottom surface of the roadway 9, thereby improving the stability of the automatic explosion-proof door-type following moving device against impact.
[0064] In this invention, "following the machine" refers to the coal mining machine at the coal face, which can move forward continuously as the coal mining machine advances. In other words, it moves forward continuously as the coal mining face advances. "Gantry" in this invention refers to the fact that the support panel 21, hydraulically retractable support legs 24, support rods 25, scissor structure 26, and traveling wheels 27 can form a portal frame structure that matches the shape of the rectangular cross-section roadway 9, without affecting the normal passage of personnel and materials underground or the normal operation of underground equipment in the roadway 9.
[0065] Of course, the above description is only a preferred embodiment of the present invention. The present invention is not limited to the above-described embodiments. It should be noted that any equivalent substitutions or obvious modifications made by those skilled in the art under the guidance of this specification fall within the scope of this specification and should be protected by the present invention.
