Inaccurate drilling set-up and hole length can cause misalignment of the whole tunnel, blasting difficulties, and can lead to over-break and under-break. Fixing tunnel alignment later is extremely expensive and it also increases the need for rock support and the risk of rock fall.
Sandvik TMS+ Boom Instrumentation systems allows the operator to control with great accuracy the drilling direction. It can also display information about hole depth, penetration rates and cumulative drilled length (”DDS” option).
Get optimal control over the drilling angle and positioning in order to avoid tunnel misalignment, as well as over-break and under-break.
Optimize ore recovery, advance per blast and the fragmentation process.
