Sandvik launches updated iSURE® 8.0 underground rock excavation software

Sandvik’s iSURE® underground rock excavation software is a purpose-developed excavation process control tool for providing instrumented face drilling rigs with all the necessary information for optimised drilling & blasting. iSURE works seamlessly with Sandvik’s iSERIES drilling rigs, combining pull-out analysis with the rig’s data collection tools and providing an accurate analysis functionality to improve the work cycle and process. The latest version, iSURE 8.0, has many new features and tools to further assist geological interpretation.

iSURE software (Intelligent Sandvik Underground Rock Excavation software) is a computer program for tunneling, construction and mining drill and blast process control, producing all the data needed for optimising the drilling and blasting cycle. Among other design tools, iSURE 8.0 has a template-based drill plan generation tool that takes into account rock blastability, tunnel profile, quality target and explosives used. The key lies in the fact that successful operations consist of four essential points – quality, cost, schedule and safety – and iSURE 8.0 is designed to help ensure that the best results are achieved, by making drilling and blasting even more accurate.

Optimisation of drill and blast means taking into consideration the changes in rock blastability and other changes in the environment. An effectively-controlled blast results in good pull-out, a restricted fracture zone and greater rock strength around the tunnel. Furthermore, rounds’ length and detonation can be tuned to the permitted vibration level and geology. iSURE 8.0 helps to achieve this, as it provides a set of plan templates for editing and feedback functions to achieve the best possible result from the blast, with blast patterns being easily edited to match the design parameter.

 iSURE 8.0 enables drill rig usage and drilling process efficiency to be maximised, assessed and measured on a round-by-round basis. Counters for percussion, power pack, drilled metres and net penetration, as well as average and gross drilling capacity [m/h/boom], are collected for each boom. A round’s duration is divided into main categories for navigation, drilling, boom control, idle time, or booms not finishing the job at the same time, further allocating them into sub-categories for drilling and boom. This provides valuable feedback that helps to finetune the rig’s behaviour, while also acting as a learning tool for operators.

The program further assists in the analysing of data collected along tunnel line, which reveals the trends of various KPIs. In addition, analysing the ‘measure while drilling’ (MWD) items gives a histogram report of the achieved penetration rate for the used drilling power, flushing sufficiency or disturbances in drilling, both in general terms and each boom.

All of these features are achieved through the full-featured iSURE 8.0 software utilising the drill rig’s data collection, thereby improving the work cycle and the drill and blast excavation process. It also has an optional toolset for geological analysis (iSURE GEO), a tunnel profile 3D scanning system (iSURE 3D SCAN) and an interface to a third-party blasting vibration feedback system. iSURE 8.0 software capitalises the state of art accuracy of Sandvik’s advanced iSERIES rigs for drill and blast.
