Underground mines and Tunneling: DEPREUX

Depreux is worldwide one of the two or three major suppliers of belts to the underground mines.

We supply the widest range of safety belts in the world, all strictly in compliance with the standards and norms for every country related to the use of belts in underground mines.

The most popular standards for underground belts are: DIN, PN, BS, AS, MT, MSHA, GOST, etc. For details please contact our sales department.

In the field of tunneling, in most applications the conveyors are very narrow. They extend to become very long as the works progress.

Hence the belts are both narrow and of high tensile strength. Often the conveyors have as well horizontal curves.

And finally, in most applications fire-resistance of the belt is required - American MSHA or German Din K.

Type of belts Range in tensile strenght
Multiply or straight-warp textile belts Up to 3150N/mm
Pressed and non-pressed solid-woven PVC covered belts Up to 3150N/mm
Solid-woven PVG rubber covered (chloroprene or nitrile) belts Up to 3150N/mm
Steel-cord belts Up to 6300N/mm

Indian Tunnel

Depreux has developed some original solutions and is now recognized to be one of the main suppliers in this market segment.

As an example, we supplied Robbins (USA) 20 km of a single ply 1000 N/mm straight-warp DX-FLEX belt. This belt was ultra thin and yet very robust and resistant to various potential hazards.

Standard and specialised belts for the Underground mines and Tunneling:

We supply:

  • plied DELTAFLAM, in DIN K or MSHA

  • plied cross-foot weave DELTAFLAM (CFW) in DIN K or MSHA

  • straight-warp DXFLEX

  • steel-cord DX/ST with or without textile or steel-breaker.
