DTI GroundBlaster™ is an accurate compound angle calculation system utilized in underground mining angular or plain blast pattern developments. It accurately calculates the entered Ring and Dump angles of the individual holes of the project. Angle data is stored for future recall no matter the amount of time the drill is away from the worksite, days weeks, or months.

The operator simply uses touch screen instructions to precisely transfer angular setup information from the first selected hole to the remainder of the pattern without having to leave the cab or make any adjustments to specific mine oriented reference points.

The GroundBlaster system calculates new or existing project hole setup angles "regardless of the positioning of the drill" insuring that all blast holes are in the same plane.

The DTI Tri - Axis Angle Indication sensor allows the operator to arrive at a precise angle by reading and monitoring; Ring, Dump, and Azimuth movement angles (fig. 1), as well as a combinations of all three angle planes, (known as compound movement angles). The results are accurate drilling (less bad holes), time, and cost saving, record, and data storage.
