About


Flame-Retardant Polymer Grids for Mining Protection

ACEGrid® FR are flame-retardant, high-strength, flexible, and lightweight polymer grids used to replace traditional metallic meshes or fences, such as metal mesh and steel, as supplemental ground, highwall, roof, or rib supports in underground openings. Compared to metal mesh, ACEGrid® FR offers advantages such as being lightweight, corrosion-resistant, and easier to install. ACEGrid® FR is also suitable for use in soft rock mining environments due to its flexibility and high tensile strength. Additionally, they are used especially for long wall shield recovery in coal mines and other mines, where rock bolts and cables are used as the primary support and supplemental support by wire meshes. ACEGrid® FR can be applied for both permanent support and temporary support applications, providing long-term stability and safety in various underground excavation projects.

Features

Enhance the safety of mining environments

ACEGrid® FR are grids woven of high-tenacity multifilament polyester yarns. They can provide a wide range of tensile strength from 20kN/m to 800kN/m. The grids are coated to enhance properties such as fire resistance and static conduction, with coatings composed of flame retardant and/or anti-static polymers, depending on the job site needs or government guidelines. In addition to their flame retardant and anti-static properties, ACEGrid® FR also offers excellent alkali resistance, ensuring long-term durability in harsh mining environments. These grids can reduce the scale of fire accidents and diminish the spread of fire that may occur in a combustible mining environment. The positive effect of ACEGrid® FR is seen in improved mining safety and operational efficiency. Most significantly, they are free from Halogen and Sb2O3, which may release highly toxic gases when in combustion.

ACEGrid® FR grids are tested to meet or exceed industry safety standards for flame resistance and mesh thickness. These certifications ensure consistent fire behavior under emergency conditions, aligning with global mine safety regulations. The flame-retardant coating has high LOI rating in accordance with industry standards, which suppresses combustion in low-oxygen environments typical of underground operations.

Furthermore, ACEGrid® FR grids are flexible and have no sharp edges, making them easy to handle and install. This allows for quick and convenient installation of ACEGrid® FR, saving time and effort on-site. Their reliability in demanding mining environments ensures consistent performance and enhanced safety for miners and equipment.

Strong and stable support in the long term

The polyester yarns used to produce ACEGrid® FR offer very high tenacity and premium quality. Additionally, with expertise in geogrid manufacturing, ACEGrid® FR is engineered to achieve high tensile strength even at low strain levels. Thus, the grid has great tensile modulus performance for being the support components, making it suitable for use at different levels of mining operations, including deep-level mines.

The creep resistance of ACEGrid® FR under sustained load has been validated through long-term tensile creep tests, confirming its performance over decades. The low-creep polyester yarns maintain structural integrity even when subjected to dynamic mining loads, enabling it to function effectively as part of the integrated ground support system.

In comparison to metallic meshes, the polymer grid is rust-free, light in weight, and has high resistance to chemical corrosion. The use of ACEGrid® FR in mining tunnels can also help reduce ventilation resistance and save energy, supporting more efficient underground operations. Its application is especially relevant for the mining industry, where tailored support systems are essential for underground mining environments.

Increase mining production efficiency

The dimension of ACEGrid® FR grids can be modified within the range of 1-5m for width and 50-400m for length to match the sizes of mine work faces, and can accommodate various widths of mining entries or galleries. In addition, the tensile strength of the grid can be designed with variety to fulfill the requirements of mining protection and grid installation.

ACEGrid® FR's low profile and reduced weight make it compatible with mechanized installation systems, reducing manual labor and installation time. Its compressible nature allows it to be rolled and transported easily into narrow mine shafts, increasing logistics efficiency compared to rigid metallic mesh.

ACEGrid® FR is also highly suitable for use in coal mine and tunnels support applications, providing essential safety and stability.

Why ACEGrid® FR is the right mining mesh for your operation 

 

Engineered for Demanding Underground Conditions

Selecting the right mining mesh is a crucial step in ensuring the safety and efficiency of your coal mining operations. When evaluating options, it’s important to consider the specific demands of your mining environments, including the need for high tensile strength, corrosion resistance, and flame retardant properties. A mining mesh with an anti-static coating is essential for coal mines, as it helps prevent static-related hazards that can compromise safety. Additionally, alkali resistance is vital for maintaining the mesh’s integrity in challenging underground conditions.

Performance that Outlasts Metal Mesh

Comparing different types of mesh, such as metal mesh and advanced alternatives, allows you to assess which solution offers the best balance of permanent support, protection, and cost-effectiveness for your operations. Unlike galvanized steel mesh, ACEGrid® FR does not suffer from oxidation or coating delamination over time, even in high-sulfide or wet mine environments, where traditional metals deteriorate quickly.

Proven Track Record and Reliable Support

Look for proven reliability and a track record of performance in similar mining environments to ensure you are investing in a mesh that will deliver long-term benefits. Consider the ease of installation, ongoing maintenance requirements, and the overall cost to make an informed decision. By prioritizing these factors, you can select a high-strength mining mesh that is ideal for your coal mining needs, providing robust support and enhancing the safety of your workforce.

Technical and Environmental Excellence

Having more than 20 years of experience in manufacturing geogrids and research effort on environmental issues of raw materials, ACEGrid® FR has proven to outstand in terms of excellent mechanical behaviors, durability, quality, cost effectiveness, profitability for mining companies, and environmental friendliness.

The company has a strong international presence, serving clients across the world and is recognized as a global provider in the mining support industry. The benefits of using ACEGrid® FR include:

Simple and quick installation to reduce construction costs and increase work efficiency, with the use of specialized devices for installation
Well-functional in mining environments in the long term to reduce maintenance costs
Robust, steady and durable to enhance worker’s security, reduce injury, and minimize downtime in mining operations
Halogen and Sb2O3 free to diminish the harmful threat to the miners and our Earth
