The Wassara technology uses water to power the down-the-hole (DTH) percussion hammer.
This makes it the superior choice for many drilling applications where air-powered DTH hammer, top hammer or rotary drilling equipment are normally used.
Drilling technologies over the years
The mechanised drilling in mining operations started some 140 years ago with the invention of the pneumatic top hammer. Productivity demands have forced development in new technologies, and the possibility to drill long and straight holes gave a huge step in this direction. The most recent major innovation in drilling came with the water-powered DTH hammer from Wassara.
Wassaras water-powered DTH hammer is the most environmentally friendly percussion drilling method existing today. The DTH hammer is powered by water. No oil is used for lubrication, meaning no contamination of air or water. The water is effectively suppressing dust as well.
The incompressibility of water is a key factor allowing the features of the Wassara hammer system. It also gives a major energy cost saving compared to air DTH technology, and reduces the energy demand to power the hammer
Wassara applications
A selection of applications where drilling with Wassara makes a difference:
