1. Underground coal mines:

Due to the harsh working environment underground in coal mines, which contains gas and coal itself is flammable, the primary consideration when selecting a conveyor belt is ensuring safe and stable coal transportation. Underground conveyor belts must be flame-retardant and have obtained safety markings and production licenses.

Currently, there are two main types of flame-retardant conveyor belts used in underground coal mines: fabric-cored flame-retardant conveyor belts and steel-cored flame-retardant conveyor belts.

Fabric-cored flame-retardant conveyor belts offer excellent flame-retardant properties, effectively preventing fire accidents and ensuring production safety. They are generally made of high-strength fabric and flame-retardant rubber. They offer excellent flame retardancy, antistatic properties, water resistance, moisture resistance, tear resistance, thinness, low weight, and low energy consumption. They are suitable for material conveying in industries such as coal mining, chemicals, power generation, metallurgy, and building materials.

Flame-retardant steel cord conveyor belts also offer excellent flame-retardant properties. When exposed to open flames or high temperatures, they resist combustion and produce no toxic smoke or harmful gases, effectively preventing the spread of fire and casualties. Furthermore, they offer excellent anti-static properties, high tensile strength, impact resistance, minimal elongation, excellent troughing properties, excellent flex resistance, and a long service life, meeting diverse working environments and requirements.

2. Surface and open-pit coal mines:

Unlike underground coal mines, conveyor belts in surface and open-pit coal mines are no longer required to be flame-retardant or anti-static. Instead, they prioritize physical, mechanical, and safety properties. Layered conveyor belts and steel cord conveyor belts are preferred.

Layered conveyor belts are made of multiple layers of rubberized canvas bonded together and covered with rubber, which is then vulcanized to form a single unit. They offer high load-bearing capacity, long service life, strong adaptability, and easy maintenance. They are suitable for conveying bulk, granular, powdery, pasty materials, or piece goods in ports, docks, airports, warehouses, and other industries.

Steel cord conveyor belts are made of a core rubber, steel cord, a cover, and side rubber. They feature high tensile strength, excellent impact resistance, long life, minimal elongation, excellent troughing, and excellent flexural resistance. They are suitable for conveying materials over long distances, at high speeds, and are widely used in coal, mining, ports, metallurgy, power generation, and chemical industries.
