Drilling long straight holes with Wassara

Long straight holes

Regardless of tunneling method, traditional drill and blast or Tunneling Boring Machine (TBM), there is a need to drill long straight holes in order to minimize stops in production for surveying and grouting purposes. The water-powered DTH hammer from Wassara has a proven track record of its ability to drill long straight holes while maintaining performance throughout the entire hole length.

 

Drills through difficult formations

The water-powered DTH hammer can penetrate hard, soft and fractured rock as well as water-rich formations with high back pressure.

 

High drilling performance

A Wassara water-powered DTH hammer will maintain a high rate of penetration in most formations. The Wassara hammer performance is unaffected by water in the formation.
