ELGi has been providing reliable compressed air solutions to the water well segment for more than forty years. For DTH drilling, the compressors meet the critical requirements of faster penetration, reliable performance and fuel economy. Integrated Air Solutions is a leading supplier of advanced, reliable and efficient high pressure diesel-driven air compressors for the drilling industry and the regional sales and service partners for ELGi. Torque Africa Drilling, a well-known specialist driller, recently carried out a drilling operation to drill vertically down into an old mine shaft to dispose of acid water for the Department of Water and Sanitation. This was done using two ELGi 1100 cfm compressors arranged in tandem to drill 1,148m vertically down into the mine shaft. The site of this super deep borehole is in the Eastern Basin acid mine drainage (AMD) treatment plant, in Springs, Gauteng.
“So far this is the deepest confirmed hole I have ever seen - or other drilling companies have ever made, in this kind of rock formation in the country,” said Torque Africa Drilling’s Nardus Bezuidenhout.
Bezuidenhout said he has been in the drilling industry for almost twenty years and it is not easy to go even beyond 300m deep in this rock formation. “Although the original plan called for a vertical hole of 700m, a new target of 1,200m was set, and the target was acquired at 1,148m with the ELGi compressor.”
“The compressors are powered by ELGi’s own axis airends that improve energy efficiency and reduce maintenance cost, and have robust enclosures to withstand heavy use”, says Bert Stewart, General Manager of Integrated Air Solutions. “Their compact design and light weight means they can be easily mounted onto drilling trucks and are very suited for applications such as water well drilling. They also have user-friendly centralised control panels and quick and easy access to routine maintenance points.” ELGi is one of the few companies in the world to offer the full line of single and two stage compressors in this range. ELGi compressors are widely used by drill rig OEMs globally.
