New thinking of revolutionary underground engineering with accuracy

In the future, the importance of underground facilities construction to improve the quality of life will become more and more prominent. As urban traffic and parking lots gradually turn underground, tunnels will make the urban environment we live in cleaner and safer.

Compared with ground construction, the cost and risk of underground operation both increase. No one can accurately predict the impact of excavation on the ground. Nevertheless, it is not difficult to ensure safe, efficient and environmentally friendly excavation as long as appropriate equipment is used to advance the project in an orderly manner.

Sandvik DTi series intelligent rock drilling jumbo is used to dig tunnels with 12-211m2 cross section, which can be used for heading drilling, anchor drilling and mechanized deep hole drilling. Its design focuses on ease of operation. Together with iSURE® tunnel management software, intelligent drilling control system, high-frequency RD525 rock drill, high-strength boom and advanced drill pipe guidance, it achieves the best quality excavation results at the lowest cost.

Intelligent manufacturing technology has become the objective trend of the development of manufacturing industry in the world, and sandvik iSURE® tunnel excavation project management and information analysis software is a cornerstone of intelligent tunnel gold digging. It is a revolutionary new tool software for tunnel and mine construction, and provides a tool for continuously optimizing the hole layout in actual production with a new concept. And generated all the necessary information to continuously follow up and improve the drilling and blasting cycle.

Using iSURE® to design the hole layout diagram and blasting diagram is based on the required charge density, different tunnel sections, the charge weight and explosive energy of each hole, and the depth of blasting fracture zone caused by different charges. ISURE® software calculates the resistance line and hole spacing according to the hole bottom that needs the maximum blasting energy. Its powerful function and automatic calculation ability make the modification and editing of hole layout diagram and blasting diagram simpler and faster.

ISURE®I tunnel module can quickly design the layout diagram of blasting holes and deep holes in tunnel face. Combined with IsureII report and iSURE®III analysis module, iSURE® has become a powerful tunnel management software, which makes it easier and more efficient to store, analyze and combine all data related to drilling and blasting. The last module, the combination of iSURE®IV anchor and DTi drilling rig, can be used for the design of anchor hole layout and the collection of anchor hole data.
