Rehabilitation of Mine Acid Water drainage Solar Pumps

Posted in News

KG ELECTRIC is currently completing  an order to rehabilitate a damaged solar pump system to drain acid water at an old coal mining site for BHP Billiton (Mine Closure Operations) near Witbank.

PROJECT DESCRIPTION:
The pumping well point is located near a natural stream into which the acid water would otherwise flow. It is an collection area which was constructed by means of digging up the ground and filling it with rocks around the pump point ( pump chamber). The acid water gathers into this area into the spaces between the rocks.

From the pump chamber it is solar pumped to higher terrain into old underground mine-workings ( shafts).

From there it is then transferred by gravity and/or further pumps to a treatment plant. Lime is added to the water to neutralize the acidity, and then may be treated further to obtain drinking water, or it is released back into the natural streams

PUMP DETAILS
Pump system: 2 X LORENTZ PS4000-C-SJ30-2
Water Source: Mine acid water
Total Dynamic Head: approximately 20m
Daily Flow rate: approx 200cum/day per pump ( annual average)
Pipe length: approx 300m
Tank Size: N/A – underground reservoir

PV GENERATOR
Panel Model: Kyocera KD135SX-1P, 135Wp
Quantity: 2 x 32
Power in total: 8.64 kWp
