1. Coal Mine Plastic Support Mesh
Product Description:
Steel-plastic composite support mesh for coal mines, manufactured via flame-retardant and antistatic treatment of PE resin and carbon steel wires, formed into an integrated grid structure through plastification and extrusion processes.
2. Steel-Plastic Composite Support Mesh for Coal Mines
Product Description:
Identical composition and production process as Item 1, engineered for underground reinforcement applications.
3. Bidirectionally Stretched Plastic Support Mesh for Coal Mines
Product Description:
Specifically designed for false roof support in mining faces and roadway reinforcement. Manufactured from polymer-modified compounds via biaxial stretching, offering:
- Lightweight yet high-tensile strength
- Isotropic mechanical properties
- Flame-retardant and antistatic features
- Corrosion resistance
4. Mine Filling Fabric (Flexible Formwork for Pumped Concrete, Hongxiang Patent)
4. Mine Filling Fabric (Flexible Formwork for Pumped Concrete, Hongxiang Patent)Product Description:
High-strength industrial filaments treated with flame-retardant/antistatic technology, woven into reinforced fabric with uniformly distributed reinforcement ropes. Customized into double-layer flexible formwork boxes to replace traditional templates for:
- Concrete filling and shaping
- Fragmented roof/coal seam support
- Gob isolation and roadway reinforcement
Engineering Construction
1. Installation of Bidirectional/Steel-Plastic Support Mesh
- Level the mining face;
- Lay mesh flush against surrounding rock;
- Drill bolt holes through mesh apertures;
- Install bolts with trays and tighten nuts;
- Secure auxiliary supports.
2. False Roof Mesh Installation
Follow Steps 1-4 above. Mesh connections use:
- Plastic ropes
- Binding wires
- Connection buckles
3. Flexible Formwork Application
- Fabricate double-layer fabric formwork to design dimensions (leaving one open end);
- Fill with concrete via pump, pneumatic delivery, or manual placement;
- Compact by vibration for curing and structural support.
