Reverse Circulation is the most commonly employed drilling method for grade control in open pit mining operations. This type of drilling is utilized to better define the information already available on the ore grades and ore blocks on the mine in order to optimize ore extraction as well as mine planning and blasting patterns.
Grade control drilling’s main purpose is to better define the ore grades within the mine and refine the information obtained and inferred from the resource block model of the mine.
Surface manager allows one to measure various parameters during drilling and can be accessed in real-time through the Certiq telematics system
Roc manager software allow rock mass modelling from information gathered from surface manager. Ex. Penetration rates can be correlated to hardness in order to estimate waste to ore ratios in blastholes.
Certiq hardware mounted on the D65 transmits data gathered from the Rocma and Surface manager and allows user to view data in real-time on Certiq portal.
