Case Study: Rio Metro achieves on-time, safe metro shaft completion with Master Drilling

Rio Metro completes 3 ventilation shafts on time and without deviation with Master Drilling Group Ltd

Rio Metro required three new ventilation shafts for the extension of the Rio underground metro. The challenge involved drilling these deep shafts without deviation, operating under strict time and noise restrictions due to the site's proximity to residential areas. Master Drilling Group Ltd was engaged to perform the raise boring work.

Master Drilling solved the access issue by building custom ramps and successfully drilled the shafts while adhering to the limited operating hours and noise constraints. The project was completed on time, within budget, and without any deviation from the planned path. Master Drilling also achieved a 100% safety record for the entire project duration.
