raise boring machine
Key technologies of drilling process with raise boring The progress in raise boring technology needs to address many important issues about basic theory and key equipment of raise boring machine. According to the drilling process of the conventional raise boring machine, a series of rock mechanics problems should be concerned, including stability of hole wall, interaction of drill string and rocksMaster Drilling ServicesAbility to bore a shaft blindly as opposed to sinking methodology. Quicker, safer and more cost effective than conventional methods. Entails the use of a raise boring machine, reverse circulation modified rods, a down reamer, and mud circulation and compressor systems for air lift, flooded hole concepts.

Raise boring equipment rocktechnology.raise boring equipment • Pilot drilling Conventional raise boring begins with the drilling of a pilot hole. It is drilled using a roller bit with sealed bearings, together with hollow drill pipes 1.5 m in length with an international standard thread for high–torque appliions.Appliion of raiseboring for excavating horizontal repository. Raise boring has also been used to excavate horizontal tunnels in hard rock. Similar tunnels but of different size and different underground environment have been proposed for use in the KBS3 concept instead of Drill and Blast or tunnel boring (TBM) to excavate the deposition tunnels,
