Special safety requirements for belts for use in underground installations 1 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. 2 Normative references The following referenced documents are indispensable for the application of this document.
