Description

Technical Field

[0001] This utility model belongs to the field of mine backfilling and sealing technology, specifically relating to a mining filling device. Background Technology

[0002] In the mining process, in order to carry out orderly mining, prevent the underground goaf from becoming too large and causing ground collapse, and ensure the safety of mining operations, sealing and backfilling the goaf is an essential project. It is an effective method to ensure the extraction of ore and improve the quality of backfill, and it is also an important prerequisite for the smooth progress of subsequent layered mining projects and the safety of roof construction.

[0003] Currently, backfilling and sealing in horizontal tunnel mining and open-pit mining mostly rely on traditional red bricks and hollow bricks for manual construction. The disadvantages are high labor intensity for workers, large consumption of hollow bricks, and the risk of at least one-third breakage and waste during underground transportation. Furthermore, the construction of high and low walls relies entirely on manual brick handling and mixing, which poses certain construction safety risks. Even slight quality problems during brick wall construction can easily lead to wall collapse and blasting accidents, resulting in subsequent ore dilution during dredging and secondary sealing production costs. Therefore, brick-built panel walls cannot meet the technological requirements in terms of safety, construction process, and material costs. Utility Model Content

[0004] This invention provides a mining backfilling device to solve the problem that brick masonry walls cannot be quickly backfilled during existing mining backfill sealing, which easily leads to safety hazards.

[0005] The technical solution of this utility model is: a mining filling device, including a main frame, the main frame is covered with a fastening rib, the main frame is provided with a slurry blocking mesh, a plurality of transverse isolation inner supports are evenly arranged inside the slurry blocking mesh, and a vertical water filter trough is connected to the isolation inner supports.

[0006] As a further improvement of this utility model, multiple oblique spiral cold-drawn wires are provided between the water filter tank and the slurry-blocking mesh, and the spiral cold-drawn wires are movably connected to the water filter tank and the slurry-blocking mesh.

[0007] As a further improvement of this utility model, a grout-blocking geotextile is provided between the grout-blocking mesh and the main frame. The grout-blocking mesh and the grout-blocking geotextile can effectively prevent grout from entering the filter tank and causing the loss of water-containing grout.

[0008] The beneficial effects of this utility model are as follows: This utility model, through the rapid splicing of multiple main frames, enables quick installation to form a retaining wall during mining backfill sealing, improving the work efficiency of workers. Simultaneously, the water filter trough within the main frame can quickly filter out wastewater from the filling slurry in the mining area, reducing the pressure on the wall. Its vertically continuous filtration function also provides a clear visual indication of the slurry rise during filling. Furthermore, the utility model utilizes internal supports between the main frames and spiral cold-drawn wires to reduce the internal weight of the main frame while effectively improving the overall compressive strength and flexibility. This results in a thinner yet stronger wall after filling, requiring less material and preventing slurry loss, thus avoiding the safety hazard of wall collapse. This utility model has a simple structure, is easy to construct, and saves time, labor, and effort. It conserves wall-building materials and allows for rapid assembly to form the wall. The safe and reliable sealing process provides high-quality assurance for mining backfill production and has a strong practical effect in mining backfill sealing. Attached Figure Description

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0012] like Figure 1-2 As shown, a mining filling device includes a main frame 1, with a fastening rib 2 covering the outside of the main frame 1, a slurry-blocking mesh 4 provided on the inside of the main frame 1, and a plurality of transverse isolation inner supports 3 evenly provided inside the slurry-blocking mesh 4, with a vertical water filter trough 8 connected to the isolation inner supports 3.

[0013] Multiple oblique spiral cold-drawn wires 5 are provided between the water filter tank 8 and the slurry-blocking mesh 4, and the spiral cold-drawn wires 5 are movably connected to the water filter tank 8 and the slurry-blocking mesh 4.

[0014] A grout-blocking mesh 4 and a grout-blocking geotextile 6 are provided between the main frame 1. The grout-blocking mesh 4 and the grout-blocking geotextile 6 form a double-layer protection, which can effectively prevent water-containing grout from entering the filter tank 8 and causing grout loss.

[0015] When sealing the entrance of a mining tunnel, firstly, drill holes at appropriate locations at the entrance and pre-install connecting anchor bolts. After measuring the entrance height to ensure the modules match, erect the main frame 1 inside the pre-installed anchor bolts. Simultaneously, use wire to tie the outer fastening reinforcement 2 of the modules to the pre-installed anchor bolts on the top and side walls of the entrance. Continue tying and binding subsequent modules to the anchor bolts on the other side wall in sequence. For intermediate modules, not only should the modules be securely tied to each other, but also to the top wall anchor bolts. Once the module wall is formed, finally fold the reserved portion of the bottom mesh laid in the entrance upwards and tie it to the modules. This forms an overall connection around the perimeter. If necessary, tie a certain amount of φ18 threaded steel in a grid pattern on the outer main reinforcement mesh 2 wall surface of the modules to enhance the integrity and reliability of the wet sprayed wall module.

[0016] During use, the wet-sprayed slurry will generate a large amount of water, which will penetrate into the internal water filter tank 8. The water filter tank 8 can drain the wastewater and reduce the pressure on the wall panel. The staff can visually observe the water filtration effect by observing the rise of the slurry during filling.
