Description

Technical Field

[0001] This utility model relates to the field of coal mine tunnel technology, specifically a structure for constructing a water-filled tunnel for coal mine water prevention and control. Background Technology

[0002] In coal mining operations, water control is one of the core aspects of ensuring safe production in the mine. The construction of water filling channels, as a key component of the water control system, directly affects the efficiency and safety of water control operations due to its structural rationality, ease of construction, and operational stability.

[0003] With increasing coal mining depth and expansion of mining areas, the underground roadway environment becomes increasingly complex. Coal mine roadways are not linear; due to geological constraints, they often have multiple bends and slope changes. Their angles and lengths cannot be flexibly adjusted according to the roadway's direction. Existing channel structures have simple transitions at bends and special geological formations, often employing right angles or fixed angles, which easily create dead zones for water flow and areas of concentrated pressure. In areas with unevenly developed water-conducting fracture zones, this design leads to uneven water flow velocity distribution, increasing local scouring and pressure loss, affecting the overall effectiveness of the water control system. Furthermore, existing water-filling channels are mostly integral structures; if any component is damaged, disassembly and replacement are troublesome, resulting in high maintenance costs and affecting the continuity of water control operations. At the same time, the transportation and storage of integral structures are difficult, especially when underground roadway transportation is restricted, making rapid transfer and temporary adjustments difficult, and failing to meet the needs of dynamic water control operations in coal mines.

[0004] To address these issues, this utility model provides a structure for constructing a water-filling channel for water prevention and control in coal mines. Utility Model Content

The lower mounting base has a first mounting slot, in which the first ball joint is movably connected and its angle can be adjusted along the slot. By rotating the first ball joint and sliding with the first slider, adjacent base units can be spliced ​​at multiple angles to adapt to the bends in the tunnel. The upper mounting base has a water guide port, and the upper end of the upper mounting base has a water guide groove. The water guide port is connected to the water guide groove. The water guide groove receives seepage water from the roof and discharges it into the channel through the water guide port, forming a top flow path to prevent seepage from affecting drainage efficiency.

[0008] Preferably, the upper mounting base has a first sliding groove, the upper mounting connector is fixedly connected to the upper mounting base by bolts, and the lower mounting connector is fixedly connected to the lower mounting base by bolts.

[0015] Beneficial effects

[0016] This utility model provides a structure for constructing a water-filling channel for water control in coal mines. Compared with the prior art, it has the following advantages:

[0017] (1) A structure for constructing a water-filling channel for water prevention and control in coal mines, which uses a modular design of upper and lower mounting bases as basic frame units. Individual frame units can be assembled in advance and then spliced ​​on-site in the mine. There is no need to use complex processes such as overall casting or welding, which greatly simplifies the underground construction process and reduces complex operations in the confined space of the mine, thereby effectively reducing the difficulty and intensity of construction operations.

[0018] (2) A structure for constructing a water-filling channel for preventing water in coal mines, which uses a combination of a first ball joint, a first mounting slot, a first slider, and a second chute. The angle of adjacent units can be directly adjusted by the free rotation of the first ball joint in the first mounting slot. The distance and angle of the units can be finely adjusted by the sliding of the first slider in the second chute. In the end, the channel can flexibly turn with the curves of the roadway, avoiding the formation of dead angles and pressure concentration areas. The overall structure does not need to be redesigned due to changes in the roadway direction, thus significantly improving the adaptability of the structure to the complex roadway direction of coal mines.

[0019] (3) A water-filling channel construction structure for coal mine water control, through the double waterproof design of the second waterproof cloth and the first waterproof cloth, can be manually pulled out and attached to the inner wall of the channel, thereby effectively blocking water from seeping into the inner wall of the channel or the gap between the components, avoiding softening of the surrounding rock of the roadway or damage to the equipment due to water seepage; at the same time, through the water-guiding rubber pad on the side end of the mounting base of the lower side, the water in the channel is directly guided to the preset drainage direction, preventing water from accumulating at the bottom of the base. Combined with the water-guiding groove in the mounting base of the upper side that is connected to the water guide, a multi-path guiding structure of bottom water guidance and top drainage is formed, thereby accelerating the water discharge efficiency, avoiding water accumulation in the channel from affecting the drainage effect, and further ensuring the stability and reliability of coal mine water control operations.

[0054] Manually pull the second waterproof cloth 28, causing the first connecting ring 27 on the mounting rod 26 to slide in the first sliding groove 5 and the second connecting ring 29 to slide in the fifth sliding groove 16, so that the second waterproof cloth 28 is fully unfolded and covers the inside of the channel, ensuring the waterproof effect.

[0055] The first connecting rod 23 is adjusted synchronously to unfold the first waterproof cloth on it, which then works with the second waterproof cloth 28 to form a complete waterproof system.

[0056] Check the water-guiding rubber pad 12 on the side connecting bracket 11 of the lower mounting base 2 to ensure that it is installed in place and can effectively guide the water flow.

[0057] Check the water inlet 31 and water channel 32 on the upper mounting base 1 to ensure that they are well connected and can assist in water flow.

[0058] Water channel trial operation:

[0059] A water flow test was conducted to observe whether the water flow could be smoothly guided by the water guide rubber pad 12, and then smoothly discharged through the water guide port 31 and the water guide channel 32.

[0060] Check all connections for leaks; if any are found, adjust the relevant components promptly.

[0061] Confirm whether the sliding components such as the first connecting ring 27 and the second connecting ring 29 are stable under the impact of water flow to ensure the overall reliable operation of the channel.
