When the LKAB mine needed to drill long utility holes they choose Wassara for the job.
As in all underground mines, there was a need for long utility holes at LKAB Malmberget. The Wassara water powered DTH drilling system is the preferred method when connecting different sub-levels with electrical service, communication, water drainage etc.
With a Wassara drilling system, it is possible to drill straight holes without sacrificing performance and also gaining a better working environment as a bonus.
