Inaccurate drilling set-up and hole length can cause misalignment of the whole tunnel, blasting difficulties, and can lead to over-break and under-break. Fixing tunnel alignment later is extremely expensive and it also increases the need for rock support and the risk of rock fall.
Sandvik TCAD+ is an aiming tool for executing on a pre-designed drilling plan, featuring face drilling, long-hole drilling and bolting-hole plans on the screen.
Sandvik TCAD+ supports different navigation methods. In addition to traditional laser and drill-bit navigation, it introduces total station navigation to standard rigs, greatly improving their accuracy. The navigation user interface is easy to use, with on-screen creation and editing of the lasers.
With its built-in data collection, TCAD+ provides information on hole position and angle logging, as well as the drilling process. By improving the accuracy of drilling, the TCAD+ enables optimization of the whole tunneling project.
The Sandvik TCAD+ includes a troubleshooting function to help test the correct functioning of the system’s sensors and the CAN system.
TCAD+ is delivered together with Sandvik iSURE®, the most sophisticated and advanced tunnel-process management software on the market. Results in accurate drilling and optimized excavation due to drilling and blasting design at the most critical position (i.e. at the end of the round). Optimizes the drilling process, as well as the complete drill and blast process. iSURE® is user-friendly and easy-to-use software.
Professional training available for operators and service with comprehensive training tools (Windows simulator).
