Wassara creates utility holes with the same precision as rotary non-percussive drilling but much more efficiently, resulting in increased productivity.

Greater precision at faster pace

Utility holes are always required in mines, particularly when amine expand with new levels. The drilled holes are required for cables, power-supply and drainage to manage the water. Utility holes have to be drilled with virtually perfect accuracy in order to reach the desired target. This is the reason, drilling methods traditionally used for regular production drilling, such as top hammers, are not optimal. Therefore, diamond-core drill rigs tend to be used instead.

This method however is not very productive as it takes a long time to achieve the desired results, and thus time spent on the coredrilling applications is reduced. This method can also cause logistical problems if drilling is blocking an entrance to a level etc. With Wassara, a similar accuracy is achieved with a 5 fold increase in productivity. In other words, the benefits of Wassara are long and straight holes with very high productivity.
