ROCK TOOLS In broad terms, Robit Sense Systems seek to add ever deeper levels of understanding and optimisation to the drilling process through digitalisation “Even as industry norms vary vastly on a global scale, the advantages of hole deviation measurement are widely recognised. Some countries are further on than others in institutionalising this, for example, in Sweden hole deviation measurement is compulsory for a minimum of the first row in a blast pattern. Beyond the obvious safety gains in ensuring predictable blasting by reducing the risk of flying rocks, the process related efficiency and cost benefits are significant. Optimising blasting is more efficient and the overall costs lower than fixing the problems down the chain in secondary breaking and crushing. Drilling then is a main determinant of a good blast, and hole deviation an integral part of blast design. Costs can essentially be cut in fuel consumption, explosives, and transportation, but also in streamlining the overall process as measuring can be integrated into the drilling process with the S Sense system.” Robit says that the strength of Sense Systems is not only derived from the above mentioned sources. “Both the M and the S are operated on a rugged tablet computer running an easy-to-use graphical interface software. The deviation information is immediately available on the tablet, but when a sim-card is inserted or the device is hooked to Wi-Fi, the data is also readily available in a cloud service. For the S Sense this means that a central office can follow the development of the drill pattern as it is drilled and start planning the blast accordingly. The cloud service is also a central location for all the drilling data, patterns and worksites and can be accessed by multiple people anywhere in the world.” As customer companies are starting to use Sense, the system and process linkages must be carefully planned, says Robit. “From a cooperation point of view it is more demanding than b
