  According to the different uses of conveyor belts, China's coal mine conveyor belts are implemented in accordance with the national standards, coal industry standardized industrial standards.
    (1) the national standards implemented < br />.   (1) GB/T 7984-2001 Conveyor Belt with Rubber or Plastic Covering Rubber for General Purpose Fabric Core Conveyor Belt. The standard specifies
conveyor belts for general purpose fabrics with rubber or plastic covering rubber. Specifications, models, technical requirements, test methods, inspection rules, marks and packaging. It is suitable for material transportation in coal mine surface, coal preparation plant, open pit coal mine and non-coal industry.
  (2) GB/T 9770-2001 "Steel Core Conveyor Belt for General Purpose". The standard stipulates the classification, technical requirements, test methods, inspection rules, marks, packaging and belt joints of steel cord conveyor belts for general use. It is suitable for steel wire rope core conveyor belt in coal mine ground, coal preparation plant, open-pit coal mine and non-coal industry with working environment temperature ranging from - 20 C to 40 C.
  (3) GB/T 10822-2003 Flame Retardant Conveyor Belt for General Purpose Fabric Core. This standard specifies the product classification, technical requirements, test methods, acceptance rules and markings, packaging, storage and transportation requirements of flame retardant conveyor belts with rubber covering for general use. It is suitable for general purpose fabric core flame retardant conveyor belt used in coal mine ground, coal preparation plant, open pit coal mine and non-coal industry, but not for underground coal mine flame retardant conveyor belt.

    (2) the implementation of coal industry standards < br />.
  (1) MT 914-2002 "Coal Mine Fabric Full Core Flame Retardant Conveyor Belt", including PVC, PVG Full Core Flame Retardant Conveyor Belt. The standard stipulates the product type, specification and technology of the whole core flame retardant conveyor belt for coal mine fabrics < br />.
Technical requirements, test methods and inspection rules, labels, packaging, transportation and storage, suitable for coal mine fabrics whole core flame retardant conveyor belt.

  (2) MT 668-1997 Technical Requirements for Flame Retardant Steel Core Conveyor Belt for Coal Mines. This standard stipulates the product type, specification, technical requirements, test method, inspection rules, marks, packaging, transportation and storage of flame-retardant and antistatic steel cord conveyor belt for coal mine. It is suitable for coal mine fire-retardant and antistatic steel cord conveyor belt.

  (3) MT 669-1997 Technical Conditions for Flame Retardant Wire Rope Traction Conveyor Belt for Coal Mines. This standard stipulates the technical requirements, test methods, inspection rules and signs, packaging, transportation and storage of fire-retardant steel wire rope traction conveyor belt for coal mine. It is suitable for coal mine fire-retardant steel wire rope traction conveyor belt.

    (3) the implementation of chemical industry standards < br />.
  (1) HG 2539-1993 "Flammable Conveyor Belt with Wire Core". This standard stipulates the product classification, technical requirements, test methods, inspection rules and signs, packaging, transportation and storage of the steel rope core flammable conveyor belt. It is suitable for the steel rope core conveyor belt used in coal mine ground, coal preparation plant, open pit coal mine and non-coal industry places requiring flammable and conducting static electricity.

  (2) HG/T 3647-1999 Cold-resistant Conveyor Belt. The standard stipulates the product classification, technical requirements, test methods, inspection rules and signs, packaging, transportation and storage of cold-resistant conveyor belts. It is suitable for cold-resistant conveyor belts with fabric cores in coal mine ground, coal preparation plant, open pit coal mine and non-coal industry whose ambient temperature is - 60 ~50 C.
