The usage method of galvanized mesh for mining mainly includes the following steps:
Preparation work
1. Check the specifications of the warp and weft mesh: Ensure that the specifications of the warp and weft mesh (such as size, wire diameter, material, etc.) meet the requirements of mine support.
2. Prepare installation tools: Prepare necessary installation tools such as zip ties, scissors, hammers, wrenches, etc.
Laying the latitude and longitude network
1. Determine the laying location: According to the design requirements of mine support, determine the laying location and scope of the latitude and longitude network.
2. Laying single-layer mesh: Lay the first 4 meters of single-layer mesh on the working face, paying attention to the appropriate direction and inclination of the stubble to ensure a tight connection between the mesh pieces.
3. Change to double-layer mesh: After the single-layer mesh is laid, it should be changed to double-layer mesh according to the support needs to improve the support strength.
Fixed half logs and steel wire ropes
1. Thread a half round log: When the first net is lowered onto the rack, thread a half round log along the inclination. For each step (usually 0.6 meters), insert another half round log to enhance the stability of the mesh.
2. Thread steel wire rope: When the third metal mesh is installed on the support column, thread the first steel wire rope along the inclination. After each step, thread a steel wire rope, for a total of five wires. The installation position of the steel wire rope should be determined according to the support design.
Tightening and fixing
1. Tighten the steel wire rope: Use a special tool (such as Qianbulan) to tighten the steel wire rope, ensuring that the warp and weft mesh is in a tight state to improve the support effect.
2. Fixing the steel wire rope: Use fixing devices such as ingot clips to firmly fix the steel wire rope on the bracket or rock wall to prevent it from loosening or falling off.
Inspection and adjustment
1. Check the laying quality: After the laying is completed, a comprehensive inspection of the laying quality of the warp and weft nets should be carried out to ensure that the connections between the nets are tight, free of damage, looseness, and other phenomena.
2. Adjust the support structure: Based on the inspection results and the actual situation of the mine, make necessary adjustments and optimizations to the support structure to improve the support effect and safety.
matters needing attention
1. Safety first: In the process of laying the latitude and longitude network, safety should always be the top priority, and safety operating procedures and work rules should be strictly followed.
2. Careful construction: Each step requires careful operation to ensure the safe use of the warp and weft network in the mine. Especially the fixing and tightening links must be strictly carried out according to the design requirements.
3. Regular inspection: During use, the latitude and longitude network should be regularly inspected and maintained to promptly identify and address potential safety hazards.
In summary, the method of using galvanized mesh for mining includes preparation work, laying mesh, fixing half logs and steel wire ropes, tightening and fixing, as well as inspection and adjustment. By careful construction and regular inspection and maintenance, it can be ensured that the warp and weft network plays a good role in mine support.
