MINE DEWATERING

Mine dewatering is an essential part of resource extraction, as it lowers the water table around the mine or quarry.

Mine dewatering is usually undertaken for several reasons:

• Ensures stability of mine walls during and after excavation
• Prevents flooding in underground mines

Pexgol excellent mechanical properties offer mine operators a best in class solutions. Made of a unique formulation of crossed linked polyethylene, it is resistant to creep, Slow Crack Growth (SCG), corrosion, low and high temperatures and impact. Pexgol inherit flexibility and high strain resistance, makes it resistant to failure due to water hammer.

Pexgol pipes can be supplied in long length coils (up to Ø12″) or sticks (up to Ø24″). Pipes are offered in several standard pressure ratings, and tailor made pipes can also be provided.

Pexgol pipes for dewatering applications can be used in open cast mines and underground mines as well.

Main properties of Pexgol for dewatering applications:

• Exceptional creep resistance
• Remarkable corrosion resistance: Pexgol pipes for mine dewatering can be placed directly on the ground without special precautions to protect it from corrosion
• Excellent environmental stress cracking resistance (ESCR)
• Sedimentation-free pipes
• Impervious to scratches and stone impingement (SCG)
• Features a continuous self-supporting pipe section with no need to anchor the vertical pipe section to the peer wall
• Needs very few pipe connections; sometimes, no connections necessary
• Able to transport pipe from one location in the mine to be reinserted in another location without fear of damaging the pipe
• Can be lifted and dragged to a second location
• Resistant to UV radiation – even if exposed to sunlight for the duration of pipe usage
• Operating temperatures from -50ºC to +110ºC
