Flooded reverse circulation blind boring is a versatile drilling method used for different types of shaft drilling, including production, ventilation, access, surge, and pressure shafts. All the shafts can be established without the need for bottom access. Reverse Circulation Drilling is ideal for weak ground conditions as well as water-bearing geology.
