Description

Technical Field

[0001] This invention relates to the field of mine ventilation safety technology, and in particular to an explosion-proof water bag canopy structure and its installation method. Background Technology

[0002] The "Coal Mine Safety Regulations" clearly stipulate that the distance between the explosion-proof water canopy and the working face shall not exceed 200m. During the existing fully mechanized mining operation, as the mining face continues to advance, the explosion-proof water canopy located in the conveyor belt roadway needs to be periodically moved forward to meet the regulations.

[0003] In existing technologies, the relocation of explosion-proof water canopies adopts the traditional "disassembly-transfer-reinstallation" model: first, personnel need to drain the water from the original water bags, dismantle the connection structure between the water bags and the canopy frame, then disassemble the canopy components and water bags one by one and transfer them to the new installation location, and finally reassemble the canopy frame, hang the water bags, and add clean water. Actual statistics show that this method requires a complete disassembly and installation process every 20 days on average, which presents the following problems: high labor intensity for workers; low work efficiency; safety hazards; and water waste due to draining and refilling.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Before providing a further detailed description of the embodiments of the present invention, the directional terms used in the embodiments of the present invention, such as "upper part", "lower part" and "side part", are not intended to limit the scope of protection of the present invention.

[0023] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, one embodiment of the present invention provides an explosion-proof water bag canopy structure for use in a mine, the mine including an equipment train, the explosion-proof water bag canopy structure including a plurality of explosion-proof water bag canopy units 100, each explosion-proof water bag canopy unit 100 including: A canopy beam 110, on which multiple water bag bodies 130 are movably connected; The canopy leg 120 is located on one side of the canopy beam 110 and extends away from the water bag body 130. The canopy leg 120 and the water bag body 130 are located on the same side. The end of the canopy leg 120 away from the canopy beam 110 is fixedly connected to the equipment train.

[0025] The explosion-proof water bag canopy structure is used inside a mine, including an equipment train. The structure exposes multiple explosion-proof water bag canopy units 100. Each unit 100 includes a canopy beam 110, canopy legs 120, and water bag bodies 130 mounted on the canopy beam 110. Multiple water bag bodies 130 are movably connected to the canopy beam 110. A canopy leg 120 is also provided on one side of the canopy beam 110, located on the same side as the water bag bodies 130 and extending away from the water bag bodies 130. The canopy leg 120 is fixedly connected to the equipment train, which moves the entire explosion-proof water bag canopy structure together. The explosion-proof water bag canopy structure forms a unified whole. By cooperating with the underground equipment train, the movement of the equipment train moves the entire explosion-proof water bag canopy structure, eliminating the need for disassembly, relocation, and reinstallation, thus improving work efficiency and reducing the labor intensity of workers. At the same time, there is no need for water drainage during disassembly, thus saving water resources, reducing production costs, and improving economic efficiency; it also avoids making the well slippery due to water drainage, which could affect the safety of the working environment.

[0026] Specifically, the existing "disassembly-transfer-reinstallation" method requires 8 to 12 workers per operation, and involves heavy lifting and working at heights, resulting in significant physical exertion for the workers. A single complete operation cycle can take 8 to 10 hours, during which the conveyor belt transport channel is occupied, affecting normal production and transportation. During disassembly, the need for disassembly at heights and the risk of components falling and personnel collisions during the transfer process increase the risk of accidents. Furthermore, improper operation during the emptying and refilling of the water bag body 130 can lead to water accumulation on site, increasing the risk of slipping. Frequent disassembly can cause wear or damage to the surface of the water bag body 130, increasing equipment replacement costs. At the same time, the drained clean water cannot be recycled, resulting in the waste of water resources. This application connects the canopy beam 110 to the water bag body 130 and fixes it to the equipment train through the canopy legs 120. This allows the movement of the equipment train to drive the movement of the water bag body 130, making the water bag suitable for the constantly changing fully mechanized mining face. Since the equipment train is matched with the fully mechanized mining face, it can directly drive the explosion-proof water bag canopy structure to match the fully mechanized mining face without disassembly, transportation, or reinstallation, thus reducing labor intensity, improving work efficiency, and eliminating safety hazards.

[0027] In one feasible implementation, the explosion-proof water bag canopy unit 100 further includes: The base 140 is disposed between the canopy leg 120 and the equipment train, and the base 140 is fixedly connected to the canopy leg 120 and the equipment train respectively.

[0028] Specifically, a base 140 needs to be installed between the canopy legs 120 and the equipment train. Typically, each explosion-proof water bag canopy unit 100 can have a single, integral base 140. The length of a typical explosion-proof water bag canopy unit 100 is 7000mm, or 7 meters. If there is only one base 140, regardless of its material, it will increase transportation costs and difficulties. Therefore, the single, integral base 140 can be divided into multiple smaller bases 140. This increases the contact area between the canopy legs 120 and the equipment train, improving stability during movement while reducing transportation costs and difficulties.

[0029] In one feasible implementation, the explosion-proof water bag shed unit 100 includes a plurality of bases 140, which are arranged along the length and width directions of the shed beam 110, and adjacent bases 140 in the length direction are connected by connectors.

[0030] The width of the explosion-proof water bag canopy structure is set according to the width of the equipment train, and it is usually three to five meters wide. Therefore, multiple bases 140 can be set in the width direction to increase the contact area between the explosion-proof water bag canopy structure and the equipment train without affecting the operation of the equipment on the equipment train, thereby improving the stability and reliability of the equipment train driving the explosion-proof water bag canopy structure to move.

[0031] It should be noted that in this embodiment, five bases 140 are arranged in the length direction and two bases 140 are arranged in the width direction, that is, a 2×5 array. Each explosion-proof water bag canopy unit 100 includes 10 bases 140, which are fixedly connected to the equipment train through these 10 bases 140.

[0032] In one feasible embodiment, the connector includes a first connecting rod and a second connecting rod, which are rotatably connected. The first connecting rod is fixedly connected to a first end of a base 140, and the second connecting rod is detachably connected to a second end of another base 140; or The connectors are made of solid steel pipes.

[0033] In order to achieve interconnection of multiple bases 140 and reduce the overall weight of the bases 140, thereby reducing the energy consumption of the equipment train, each base 140 can be set with a length of 1200mm and a width of 800mm. In order to ensure that each base 140 meets the requirements for supporting the canopy legs 120, adjacent bases 140 in the length direction need to be connected by a first connecting rod and a second connecting rod to meet the support requirements for the canopy legs 120. By setting two bases 140 in the width direction, the balance and stability of the support for the canopy legs 120 can be improved.

[0034] Specifically, the first connecting rod and the second connecting rod are rotatably connected, which can be a threaded connection. The first end of the base 140 along its length is fixedly connected to the first connecting rod. The second end of the base 140 along its length is provided with a through hole, and both ends of the through hole are provided with inlets that communicate with the through hole. The end of the second connecting rod away from the first connecting rod is provided with an ear block that matches the inlet. When transportation is required, each base 140 can be placed separately, and the first and second connecting rods can be placed together or transported separately. After entering the mine, they are installed by bolting the first connecting rod to the first end of the base 140. The first connecting rod and the second connecting rod are threaded together, but not fully tightened, so that the ear block of the second connecting rod is aligned with the inlet of the second end of the other base 140 to be connected. Then, the second connecting rod is inserted into the connecting hole at the second end of the base 140, and then the first and second connecting rods are tightened so that the ear block is away from the inlet, thus realizing the installation of two adjacent bases 140. It should be noted that the through hole at the second end of the base 140 is a stepped hole. The first hole near the second connecting rod is smaller than the second hole away from the second connecting rod. The diameter of the second hole matches the rotation diameter of the outermost end of the lug, thus avoiding interference caused by the lug entering the through hole and being unable to rotate.

[0035] It is understood that the fixed connection can be a bolted connection, a welded connection, or other fixed connection methods, which will not be elaborated further. The base 140 is connected to the equipment train by welding, which can be pre-welded at the rear or side of the equipment train. Two adjacent bases 140 can also be connected by multiple solid steel pipes, in which case the two ends of the solid steel pipes are respectively bolted to the base 140.

[0036] In one feasible implementation, the explosion-proof water bag canopy further includes: Support blocks (not shown), multiple support blocks are evenly arranged at one end of the canopy beam 110 away from the canopy leg 120.

[0037] Multiple support blocks are installed on the side of the canopy beam 110 away from the canopy leg 120. These support blocks are evenly distributed and typically have a size of no less than 10cm × 10cm × 50cm, made of square steel. When the explosion-proof water bag canopy structure rises to its highest working position, a rigid support structure is formed between the support frame, the canopy beam 110, and the mine roof, ensuring the canopy beam 110 is securely fastened and preventing swaying. Simultaneously, there is a reserved gap of at least 10cm between the canopy beam 110 and the mine roof, providing ample space for operations such as adding water to the water bag body 130 and maintenance.

[0038] In one feasible implementation, the canopy beam 110 includes: Crossbeam 111, a pair of crossbeams 111 are arranged in parallel; Vertical beam 112, multiple vertical beams 112 are arranged in parallel between a pair of horizontal beams 111, and multiple water bag bodies 130 are arranged on the vertical beams 112.

[0039] The horizontal beam 111 and the vertical beam 112 provide stable support for the water bag body 130. In this embodiment, for example... Figure 1 As shown, two horizontal beams 111 are provided, and a vertical beam 112 is provided between the two horizontal beams 111. The horizontal beams 111 and the vertical beam 112 are detachably connected and can be fitted with ear plates, which are fixedly connected by bolts passing through the ear plates. The water bag body 130 is hooked to the vertical beam 112 by an S-shaped hook.

[0040] It should be noted that in this embodiment, five vertical beams 112 are provided, and five water bag bodies 130 are hung on each vertical beam 112. The effective volume of each water bag body 130 is 40L, the total water volume on one vertical beam 112 is 200L, and the total volume of one explosion-proof water bag shed unit 100 is 1000L. Typically, one explosion-proof water bag shed structure includes three explosion-proof water bag shed units 100, so the total capacity of one explosion-proof water bag shed structure is 3000L, which fully meets the requirements of the "Coal Mine Safety Regulations" for explosion-proof volume.

[0041] Understandably, when using a closed water bag body 130, one vertical beam 112 is sufficient to attach the water bag body 130; when using an open water bag body 130, two vertical beams 112 are required to attach the water bag body 130 simultaneously, and the choice can be made according to actual needs.

[0042] In one feasible embodiment, the crossbeam 111 and the vertical beam 112 have the same structure, both including multiple interconnected connecting cylinder assemblies, the connecting cylinder assemblies including: A first connecting cylinder and a second connecting cylinder, the first connecting cylinder being sleeved on the second connecting cylinder, the first connecting cylinder having a slide rail on the side facing the second connecting cylinder, and the second connecting cylinder having a slider on the side facing the first connecting cylinder, the slider cooperating with the slide rail, and the two ends of the slide rail having limit blocks; Adjacent connecting cylinder assemblies can be detachably connected.

[0043] If the crossbeam 111 and the vertical beam 112 are transported as a whole, their excessive length would cause inconvenience. Therefore, the crossbeam 111 and the vertical beam 112 can be designed to be detachable or hinged, which would allow them to be folded and made easier to transport after the crossbeam 111 and the vertical beam 112 are shortened.

[0044] In this embodiment, the crossbeam 111 and the vertical beam 112 have the same structure, including multiple detachably connected connecting cylinder assemblies. Each connecting cylinder assembly includes a first connecting cylinder and a second connecting cylinder. The first and second connecting cylinders are connected by a slider and a slide rail to achieve a telescopic connection. They can be retracted during transportation. After installation, the vertical beam 112, limited by a fixed distance from the crossbeam 111, ensures that the first and second connecting cylinders are always fully extended. Simultaneously, the first and second connecting cylinders of the crossbeam 111 are also always fully extended due to the combined constraints of the canopy leg 120, the base 140, and the vertical beam 112. Adjacent connecting cylinder assemblies can be fixedly connected by bolts.

[0045] In one feasible implementation, the canopy leg 120 is a telescopic leg.

[0046] Each explosion-proof water bag canopy unit 100 uses at least four canopy legs 120, which are telescopic legs. Typically, the telescopic legs are hydraulic cylinders. The fixed end of the hydraulic cylinder is detachably connected to the base 140 via bolts, and the telescopic end of the hydraulic cylinder can also be detachably connected to the vertical beam 112 via bolts. However, in this embodiment, as... Figure 2As shown, each explosion-proof water bag canopy unit 100 uses ten canopy legs 120. One end of each canopy leg 120 corresponds to a base 140, and the other end of each canopy leg 120 corresponds to a vertical beam 112. This provides support between the vertical beam 112 and the base 140, improving the stability of the support and reducing the load on the canopy beam 110, thus increasing its service life and safety. It is understandable that whether the canopy legs 120 are connected to the horizontal beam 111 or the vertical beam 112 depends on the equipment train configuration. When the empty space on the equipment train is at both ends, the canopy legs 120 need to be detachably connected to the horizontal beam 111. When the empty space on the equipment train is closer to the middle, the canopy legs 120 need to be detachably connected to the vertical beam 112. Therefore… Figure 1 and Figure 2 This is merely an illustrative diagram.

[0047] It should be noted that when using four telescopic legs, four bases 140 can also be used, but the stability is usually poor, suitable for situations where the water bag body 130 has a small capacity. In this embodiment, each hydraulic cylinder has a maximum support height of 900mm and a minimum support height of 600mm, adapting to tunnel environments of different heights; the working pressure of the hydraulic cylinder is 16MPa, providing stable support capability.

[0048] In this application, the explosion-proof water bag canopy structure achieves self-movement of the water bag body 130 through connection with the equipment train. Each canopy beam 110, canopy leg 120, and matching connectors adopt a detachable connection design, adapting to the transportation conditions of narrow underground roadways in coal mines. The water bag nozzles can also be connected to the canopy beams 110 using quick-clamp connections, coupled with rubber sealing gaskets, to ensure a firm and reliable connection and prevent water leakage. Other units are rigidly connected to ensure the continuity and stability of the explosion-proof water bag canopy structure.

[0049] Another embodiment of the present invention provides an installation method for an explosion-proof water bag canopy structure, wherein the explosion-proof water bag canopy structure is installed underground in a mine. The installation method includes: Preliminary preparations were made, and all components of the explosion-proof water bag canopy structure were transported into the mine. Assemble the various components to obtain the overall explosion-proof water bag canopy structure; The explosion-proof water bag canopy structure is fixedly installed at the rear or side of the train; The structure of the explosion-proof water bag shed was adjusted and filled with water.

[0050] The explosion-proof water bag canopy structure described in this application facilitates installation and transportation. After reinstallation underground, the structure forms a unified whole. By coordinating with underground equipment trains, the entire structure can be moved as the trains move, eliminating the need for disassembly, relocation, and reinstallation. This improves work efficiency and reduces the workload of workers. Furthermore, the elimination of water drainage during disassembly saves water resources, reduces production costs, and improves economic efficiency. It also prevents slippery conditions underground caused by water drainage, ensuring a safe working environment.

[0051] The configuration of this embodiment reduces labor intensity and improves work efficiency when the entire explosion-proof water bag canopy structure moves with the fully mechanized mining face. The explosion-proof water bag canopy structure moves with the equipment train without disassembling the water bags and canopy frame. Each movement of the explosion-proof water bag canopy structure requires only 2 to 3 workers and takes no more than 1 hour. Compared with the traditional method (8-12 people / 8-10 hours), labor intensity is reduced by more than 70%, and work efficiency is increased by more than 80%. It also avoids high-risk operations such as high-altitude disassembly and heavy object transportation. The lifting and moving of the water bag body 130 is remotely controlled by the hydraulic system of the canopy legs 120, keeping workers away from dangerous areas. Furthermore, there is no need to empty the water bags, avoiding the risk of slipping due to water accumulation on site, significantly reducing the accident rate and improving operational safety. It reduces the frequent disassembly and wear of canopy components and the water bag body 130, extending the service life of the explosion-proof water bag canopy structure and reducing replacement costs. It also saves water resources by eliminating the need to empty the water bag body 130, and reduces the number of workers required, thus lowering labor costs. Adopting a modular design, the number of explosion-proof water bag canopy units 100 and the height of the canopy legs 120 can be adjusted according to different roadway dimensions, making it suitable for the installation of explosion-proof water bags in various fully mechanized conveyor belt roadways. The hydraulic system is compatible with the equipment train's hydraulic system, eliminating the need for additional power units and facilitating on-site application. The canopy beam 110 uses rigid connections and hydraulically stabilized supports, ensuring precise positioning after relocation. The water bag body 130 volume always meets the regulatory requirements, ensuring that the explosion-proof performance is not affected by relocation operations, providing a reliable guarantee for safe coal mine production.

[0052] In one feasible implementation, the preliminary preparations include: Conduct on-site surveys of the mine and obtain the dimensions of the explosion-proof water bag shed units based on the survey results; Based on the dimensions of the explosion-proof water bag canopy unit, the dimensions of each component are obtained, and strength tests are performed. The components were transported into the mine.

[0053] Specifically, the dimensions (height and width) of the conveyor belt roadway of the fully mechanized mining face, the structural dimensions of the equipment train, and its self-moving trajectory were first surveyed on-site to determine the installation location of the explosion-proof water bag canopy structure, the number of unit assemblies, and the specific locations of the grafting connection points, ensuring that the installation of the explosion-proof water bag canopy structure would not affect the normal operation of roadway ventilation, transportation, and other equipment. Based on the survey data and technical parameter requirements, components such as canopy legs 120, canopy beams 110, support blocks (square steel columns), hydraulic cylinders, connectors, and quick-release buckles were processed. All components underwent strength testing (especially the hydraulic cylinders, which required pressure resistance testing) to ensure that the component quality met safety standards. The processed components, water bag body 130, hydraulic pump station (compatible with the hydraulic system of the equipment train), connecting bolts, and other materials were transported in batches to a temporary storage point near the underground installation site, with proper moisture-proof and collision-proof protection.

[0054] Assemble the various components to obtain the overall explosion-proof water bag canopy structure, including: unit foundation installation, water bag body 130 suspension, and unit combination. Specifically, at the temporary storage point, the assembly of a single explosion-proof water bag canopy unit 100 is completed. First, multiple canopy legs 120 (hydraulic cylinders) are connected and fixed to the canopy beam 110 using connectors, ensuring that the canopy legs 120 are perpendicular to the bottom surface of the canopy beam 110. Then, support blocks are welded or bolted to the preset positions on the upper part of the canopy beam 110, ensuring that the support blocks are accurately positioned and firmly connected. The water bag body 130 is suspended on the preset hooks of the canopy beam 110 using quick-release buckles (or S-hooks), with 5 water bag bodies 130 evenly distributed in each row. The position of the water bag body 130 is adjusted to ensure that it is in a vertical suspension state without tilting. After suspension, a sealing test is performed on the water bag body 130 to ensure that there is no leakage. The three assembled explosion-proof water bag canopy units 100 are spliced ​​into a whole using connecting flanges and fastened with high-strength bolts to ensure that each explosion-proof water bag canopy unit 100 is tightly connected and the overall straightness meets the requirements. After splicing, the stability of the explosion-proof water bag canopy structure is checked to avoid any loose parts.

[0055] The explosion-proof water bag canopy structure is fixedly installed at the rear or side of the train, specifically including: fixing a base 140 (designed to adapt to the train structure) at the rear or side of the fully mechanized mining equipment train; the base 140 is rigidly connected to the main body of the equipment train by welding or bolting to ensure connection strength; then, the other components of the assembled explosion-proof water bag canopy unit 100 are fixedly connected to the base 140 by bolts to achieve a rigid connection between the explosion-proof water bag canopy unit 100 and the equipment train, ensuring synchronous movement of the two; connecting the multiple canopy legs 120 of the explosion-proof water bag canopy structure to the hydraulic system of the equipment train through high-pressure oil pipes, and installing a hydraulic control valve group (including lifting control buttons and pressure gauges) to achieve synchronous lifting control of each canopy leg 120; installing sealing joints at the oil pipe connection points to prevent hydraulic oil leakage; and simultaneously, setting an overflow valve in the hydraulic circuit to ensure stable system pressure and avoid overpressure damage to the cylinder.

[0056] The explosion-proof water bag canopy structure is debugged and filled with water, specifically including: operating the hydraulic control valve group to control the synchronous lifting and lowering of the canopy legs 120, and testing the stability and synchronicity of the cylinder lifting and lowering; adjusting the cylinder stroke to ensure that when the water bag body 130 is raised to the working position, the canopy beam 110 leaves a 10cm operating space from the top plate, and when lowered to the shift position, the bottom of the canopy beam 110 does not interfere with the roadway floor or other equipment; after adjusting the explosion-proof water bag canopy structure to the working height, checking the levelness and stability of the water bag body 130, and locking the canopy legs 120 through the cylinder locking mechanism to prevent the canopy legs 120 from rising and falling on their own during operation; adding clean water into the water bag body 130 through the water supply pipeline in the roadway, and observing the sealing of the water bag body 130 in real time during the filling process to avoid water leakage; after all the water bag bodies 130 are filled, checking the total volume of the explosion-proof water bag canopy structure (ensuring it reaches 3000L), completing the installation and putting it into use.

[0057] Finally, a synchronous displacement operation is required, specifically including: when the longwall mining face advances to the point where the explosion-proof water bag canopy structure needs to be moved forward, there is no need to disassemble the water bag body 130; only the canopy legs 120 need to be lowered synchronously via the hydraulic control valve group, so that the explosion-proof water bag canopy structure is lowered to the displacement height (ensuring no interference between the explosion-proof water bag canopy structure and the roof and side walls); the equipment train self-moving system is activated, and the equipment train drives the grafted explosion-proof water bag canopy structure forward synchronously. During the displacement process, a dedicated person is assigned to monitor the process to ensure that the explosion-proof water bag canopy structure and the equipment train move synchronously without relative displacement, and without... Collision with other equipment and facilities in the tunnel; after the explosion-proof water bag canopy structure moves forward with the equipment train to a position that meets the requirements of the regulations, stop the equipment train; operate the hydraulic control valve group to control the canopy legs 120 to rise synchronously, adjust the explosion-proof water bag canopy structure to the working height, and lock the oil cylinder locking mechanism; after the relocation is completed, check the stability of the explosion-proof water bag canopy structure, the integrity of the water bag body 130 and the sealing condition. If there is a small amount of water leakage in the water bag body 130, add clean water in time; after confirming that there are no problems, complete the relocation operation and the explosion-proof water bag canopy structure can continue to be used.

[0058] Example This embodiment, combined with the actual application scenario of the conveyor belt roadway of the 3201 fully mechanized mining face in a coal mine, provides a detailed description of the implementation method of this application: The conveyor belt roadway at the working face is 2.8m high and 4.5m wide. The equipment train adopts a hydraulic self-moving type, and the rear of the train has reserved connection space. According to the regulations, the total volume of the explosion-proof water bag shed structure must not be less than 3000L, and the maximum distance from the working face must not exceed 200m.

[0059] The on-site survey determined that the explosion-proof water bag canopy structure would be installed 5 meters from the rear of the equipment train. Three explosion-proof water bag canopy units (100 units each) were combined, with an overall length of 21 meters, adaptable to the tunnel width. The base (140) was designed as a welded steel plate structure, measuring 1.2m × 0.8m × 0.1m, and welded to the rear frame of the equipment train. The canopy legs (120 units, hydraulic cylinder stroke 300mm, rated pressure 16MPa), canopy beams (110 units, using 16# I-beams, 7m long each; in this embodiment, a single beam (110) was used for installation), and square steel columns (10cm × 10cm, 50cm long) were fabricated. After passing strength tests, they were transported to a temporary underground storage point in three batches. At the temporary storage point, the three explosion-proof water bag canopy units (100 units each) were assembled. Each unit (100 units) was equipped with four canopy leg cylinders, suspending five water bags (five per row). The three units (100 units each) were connected via flanges. Assemble the components into a whole and tighten high-strength bolts. Fix the entire explosion-proof water bag canopy structure to the base 140 at the rear of the equipment train using bolts. Connect the canopy leg cylinders to the hydraulic system of the equipment train using high-pressure oil pipes. Install the control valve group (located in the equipment train control room) and the overflow valve (set pressure 18MPa). Operate the control valve group to test the synchronous lifting and lowering of the cylinders, adjust the working height of the explosion-proof water bag canopy structure to 2.7m (10cm from the top plate), and lock the cylinders. Add clean water to the water bag body 130 through the water supply pipeline, with a total water volume of 3000L. After checking for no leakage, put it into use. When the working face advances to a distance of 200m from the explosion-proof water bag canopy structure, operate the control valve group to lower the explosion-proof water bag canopy structure to 2.5m (displacement height), start the equipment train self-moving system, and move the explosion-proof water bag canopy structure forward by 50m. After reaching the position, raise the explosion-proof water bag canopy structure to the working height, lock the cylinders, check the stability and water bag status, and complete the displacement.

[0060] In this implementation case, after the explosion-proof water bag shed structure is installed, it needs to be moved forward once every 20 days. Each relocation requires only 2 people and takes 40 minutes. Compared with the traditional method, it saves 60% of labor costs and reduces the operation time by 90%. During operation, no safety accidents occurred, the components of the explosion-proof water bag shed structure showed no obvious wear, the water bag body had no leakage, the explosion-proof performance was stable, and it fully met the requirements for safe production.

[0061] Understandably, if the equipment train lacks extra hydraulic interfaces, an independent hydraulic pump station (using a mine-grade explosion-proof type with a power of 5.5kW) can be added to power the canopy leg cylinders. The pump station is fixed on the canopy beam 110 and connected to the mine power supply system via cable for independent control. If the equipment train is not suitable for welding the base 140, a bolt-clamping connection mechanism can be used. High-strength bolts are used to clamp and fix the base 140 to the equipment train frame, avoiding damage to the equipment train structure caused by welding. This is suitable for scenarios where the equipment train frame is a profile structure. Depending on the tunnel width and explosion-proof volume requirements, the number of explosion-proof water bag canopy units 100 can be adjusted (e.g., 2 units or 4 units). The number of canopy legs 120 in a single explosion-proof water bag canopy unit 100 can be adjusted to 3 or 5, ensuring overall structural stability and meeting volume requirements. This is suitable for narrow tunnels (width ≤ 3.5m) or scenarios with large volume requirements (> 3000L). If the maintenance cost of the hydraulic system is high, a screw-type lifting mechanism can be used instead of the hydraulic cylinder as the canopy leg 120. The canopy leg 120 can be raised and lowered by hand or electric screw, which is suitable for small and medium-sized mines or scenarios where the lifting speed requirement is not high. This solution is lower in cost and simpler to maintain, but the lifting efficiency is slightly lower than that of the hydraulic system. A high-strength flame-retardant PVC water bag body 130 and an explosion-proof water tank can be used to replace the traditional canvas water bag body 130.
