Czech contractor Metrostav is on track to meet the planned opening of a road tunnel in remote north-western Iceland, thanks to the record-breaking performance of a Sandvik DT1131i tunnelling jumbo and iSURE® tunnel management software.
Drill and blast intelligence
Wherever accurate drilling and blasting along with drill and blast design are needed, iSURE® software and iSERIES drilling rigs make all the difference!
Successful tunneling is made of four key points: quality, cost, schedule and safety. The best tunneling results are achieved with accurate drilling and blasting together with professional design and professional people.
iSURE® software (Intelligent Sandvik Underground Rock Excavation software) is a computer program for tunneling construction and mining drill and blast process control. It produces all the data you need for an optimized drilling and blasting cycle.
Optimized drill and blast
Optimization of drill and blast means taking into consideration the changes in rock blastability and other changes in the environment. iSURE® offers a rich set of plan editing and feedback functions to achieve the best possible result from the blast. Patterns can easily be edited as the design is parameter based.
A controlled blast results in good pull out, restricted fracture zone and greater rock strength around the tunnel. A round’s length and detonation can be tuned to the allowed vibration level and geology.
Data driven productivity
Rig usage and drilling process efficiency can be studied on a round by round basis. Counters for percussion, powerpack, drilled meters, 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 – and further into sub-categories for drilling and boom. This provides valuable feedback that helps to tune the rig’s behavior while acting as a learning tool for operators.
Analyzing data collection between any two advance (peg) numbers of tunnel line reveals the trends of different KPIs. In addition, analyzing Measure While Drilling (MWD) items gives a histogram report of the achieved penetration rate for the used drilling power, flushing sufficiency, or number of disturbances in drilling – both in general or between the booms.
The full-featured iSURE® software utilizes your drill rig’s data collection to improve 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® software capitalizes the improved accuracy of iSeries rigs for drill and blast usage.
