Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing technology for filling and sealing panels in mining, and in particular to a combined module for monitoring the connection of high-strength steel cold-drawn wires to the top of wet-sprayed filling panels in mining. 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, a large quantity of hollow bricks used, and the risk of at least one-third being damaged and wasted during underground transportation. Furthermore, the construction of high and low walls relies entirely on manual brick handling and mixing, posing certain safety risks. Even minor quality issues during brickwork construction can easily lead to wall collapse and blasting accidents, resulting in subsequent ore dilution during dredging and increased production costs for secondary sealing. In short, brick-built wall systems urgently require innovative alternatives in terms of safety, construction process, and material costs. Therefore, providing a safe, reliable, cost-effective, and burden-reducing new process is imperative. Utility Model Content
[0004] The purpose of this utility model is to provide a high-strength steel cold-drawn wire filter and top-mounting monitoring combination module for mining backfill wet sprayed wall, which makes the main structure of the entire module simple, easy to construct, and saves time, labor and effort. At the same time, it has the advantages of fast assembly speed during the installation and construction of mining backfill wall, which is conducive to improving the rapid wall formation.
[0005] To achieve the above objectives, a high-strength steel cold-drawn wire filter and top-mounting monitoring module for mining backfill wet sprayed wall is provided. The module includes a main body, an outer main reinforcing mesh fixedly connected to the outer side of the main body, and an inner geotextile grout-blocking mesh fixedly connected to the inner wall of the main body. Multiple isolation inner supports and inner spiral cold-drawn wires are intersected between the inner geotextile grout-blocking meshes, and filter windows are installed between the inner spiral cold-drawn wires.
[0006] According to the aforementioned high-strength steel cold-drawn wire filter and top-mounted monitoring combination module for mining backfill wet sprayed wall, the inner spiral cold-drawn wire and the module body are interlocked.
[0007] According to the aforementioned high-strength steel cold-drawn wire filter and top-mounting monitoring combination module for mining backfill wet sprayed wall, a grout-blocking geotextile is provided on one side of the inner geotextile grout-blocking mesh, and the inner geotextile grout-blocking mesh and the grout-blocking geotextile are hung together.
[0008] According to the mining backfill wet sprayed wall high-strength steel cold-drawn wire filter top monitoring combination module, the inner geotextile grout-blocking mesh and the grout-blocking geotextile are fixedly connected by a first binding member.
[0009] According to the aforementioned high-strength steel cold-drawn wire filter and top-connection monitoring combination module for mining backfill wet sprayed wall, multiple second binding members are evenly tied to the outer side of the outer main reinforcement mesh.
[0010] Beneficial effects:
[0011] The module body has an outer ring of main reinforcing mesh on its outer side, and an inner geotextile grout-blocking mesh on its inner wall. Grout-blocking geotextile is then placed inside the inner geotextile grout-blocking mesh, and multiple internal isolation supports and inner spiral cold-drawn wires are interlaced on the inner side of the grout-blocking geotextile. This design simplifies the overall module structure, facilitates construction, and saves time, labor, and effort. Furthermore, it allows for rapid assembly during the installation of mining backfill wall panels, improving the speed of wall formation. Additionally, the wet-spraying module features a multi-functional window device for monitoring water flow at the top, enabling rapid filtration of backfill water within the mining area. The slurry wastewater can also reduce the pressure on the wall panel. At the same time, its vertical and horizontal water filtration function can monitor the rise height of the slurry during filling in real time. In addition, the unique design of hanging spiral cold-drawn wire between the two meshes not only makes it easier for the slurry to accumulate and not be lost during wet spraying of the wall panel, but also improves the overall compressive strength and flexibility of the wet sprayed wall panel. Therefore, it can also make the wet sprayed wall panel thinner and stronger, with less material and no loss. This saves wall material, and the safe and reliable sealing process provides a high-quality guarantee for mining filling production.

[0021] Reference Figure 1-4 This utility model discloses a high-strength steel cold-drawn wire filter and top-mounting monitoring module for wet spraying wall in mining applications. The module includes a main body 1, made of φ12, φ6, and φ8 round steel, 4200mm in length and 1500mm in width. An outer main reinforcement mesh 2 is fixedly connected to the outer side of the main body 1. The outer main reinforcement mesh 2 consists of a 300mm x 300mm grid formed by welding a frame and internal reinforcing φ12 round steel bars with φ6 steel bars inside. An inner geotextile grout-blocking mesh 4 is fixedly connected to the inner wall of the main body 1. Multiple internal isolation supports 3 and inner spiral cold-drawn wires 5 are intersected between the 4. The internal isolation supports 3 are located between the outer main reinforcement mesh 2 and the inner geotextile grout-blocking mesh 4. They are made of φ12 round steel, 200mm long, and welded to the main reinforcement of the two meshes. A water filter window 8 is installed between the inner spiral cold-drawn wires 5. The water filter window 8 is made of φ12 and φ6 round steel, 4200mm long and 1500mm wide. It is located in the middle of the double-layer grid module formed by the outer main reinforcement mesh 2 and the inner geotextile grout-blocking mesh 4. Spiral grout-blocking wires are hung on both sides of the water filter window 8.
[0022] The inner spiral cold-drawn wire 5 and the module body 1 are interlocked and fixed between the outer main reinforcement mesh 2 and the inner geotextile grout-blocking mesh 4 by the buckle. The wire diameter is 0.3mm and the length is 4200mm.
[0023] A grout-blocking geotextile 6 is installed on one side of the inner geotextile grout-blocking mesh 4. The inner geotextile grout-blocking mesh 4 and the grout-blocking geotextile 6 are hung together. The inner geotextile grout-blocking mesh 4 is made of φ6 steel bars welded into a 150mm x 150mm square grid. The mesh is 4200mm long and 1500mm wide.
[0024] The inner geotextile grout-blocking mesh 4 and the grout-blocking geotextile 6 are fixedly connected by a first binding member 601. The inner geotextile grout-blocking mesh 4 and the grout-blocking geotextile 6 are sandwiched and hung with the same area.
[0025] Multiple second binding pieces 7 are evenly bound to the outer side of the outer main reinforcing mesh 2. The material of the second binding pieces 7 is φ18 threaded steel.
[0026] Working principle: When sealing the entrance of a mining tunnel, firstly, drill holes at appropriate locations at the entrance and pre-install connecting anchors. After measuring the entrance height to see if the module matches, erect the main body 1 of the steel module inside the pre-installed anchors. At the same time, use wire to tie the outer main reinforcement mesh 2 of the module to the pre-installed anchors on the top and side walls of the entrance. Continue to tie and extend the subsequent modules to the anchors on the other side wall. The middle modules must not only be firmly tied together with each other, but also with the anchors on the top wall. After the module wall is formed, finally fold the reserved part of the bottom mesh laid in the entrance upward and tie it to the module. 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 module to enhance the integrity and reliability of the wet sprayed wall module.
