Case Study
OMNIx™BOLT reduces drill and blast operating costs and improves operational safety
Location: Antofagasta, Chile
Resource: Gold, Silver
Application: Underground, bench & fill method
Client Challenges & Objectives
Unplanned blasthole deviation up to 0.75m caused over-break, under-break, fragmentation and dilution. This reduced efficiency in ore recovery requiring corrective measures such as operational slots which increased operating costs.
Magnetic survey tools were generating inaccurate results and increasing operational complexity due to the requirement for cranes and additional personnel.
In cases of significant borehole deviation, blast efficiency can drop to 65%, and dilution can increase from the planned 1.0m up to 1.5m.
IMDEX Solution
OMNIxBOLT: Precise underground blasthole measurement informing better blasting outcomes.
IMDEX implemented OMNIxBOLT in the mine’s daily operations, to improve extraction, dilution, measurement efficiency and risk reduction indicators for operators.
The OMNIxBOLT combines a high-precision, north seeking gyro with a custom, manual deployment system and intuitive software to deliver a blasthole survey solution that is fast, easy to use and accurate.
