Scope

This Part of GB/T 28267 specifies the performance and constructional
requirements applicable to conveyor belts for underground mining having steel
cords in the longitudinal direction as reinforcement. The requirements for
design and construction apply to the design of single belts as well as the design
of complete type series such as those covered in GB/T 28267.2.
Steel cord belts in accordance with this Part are intended for use underground
in coal mines and in other applications where the highest demands for safety
against fire and explosion hazards have to be complied with.
NOTE At present the requirements can only be met by the use of compounds based on
chloroprene rubber for the covers as well as for the bonding rubber.
