Sandvik is looking to further optimise the drilling and blasting process with an updated version of its iSURE® underground rock excavation software.
iSURE, Sandvik says, works seamlessly with its i-series drill rigs, providing accurate analysis functionality to improve the work cycle and process. It has evolved into a renowned computer program for tunnelling construction and mining drill and blast process control, helping produce the data needed for optimising the drilling and blasting cycle.
iSURE 8.0 added a template-based drill and blast plan generation tool that considered rock blastability, tunnel profile quality target and explosives used, not forgetting designer capability to easily edit and tune the result based on the feedback of the drill and blast process, Sandvik says. iSURE 8.1 builds on this, including an in-built three-day training program to cover steps from simple concepts to the more advanced cases.
A key development sees iSURE 8.1 having a toolset for specifically covering “advanced metrics”. This helps the user increase knowledge and reveal points of improvement in face drilling rigs usage and in the tunnel excavation drill and blast process via producing high level key performance indicators from collected rounds and respective design data. These consist of production, realised schedule and heuristics analysis of the data addressing the feedback received regarding version iSURE 8.0. They are targeted to improve excavation (face drilling) production capability, plan future activities such as new projects, and to raise awareness when problems or difficulties occur.
The new and existing features found with iSURE 8.1 are designed to improve the entire drill and blast process through data collection. It will also hint if any rig adjustment is required, or if rig misuse is suspected. It shows the change in rock mass drillability, drill steel consumption, face shape after blasting and scaling, any operator deviation from the plan while drilling, and, based on scanner data, the realised profile and production volume. All this results in improved production and productive feedback that can be assessed and built upon, empowering the entire drill and blast process, the company says.
iSURE 8.1 is not the final development of this solution from Sandvik. New improvements and developments are planned based on further sharing of knowledge and experience with customers and drill and blast professionals globally, the company says.
Currently, iSURE is used with Sandvik’s i-series face drilling rigs, the original construction i-series and newer bedrock-style i-series, TCAD+ and bolting instruments.
