The complete development and construction contract for BAUER Resources Canada included the following partial services:
BAUER HPRC swivel power rotary head with six rinsing heads to mount on a drilling rig of third-party manufacture
BAUER HPRC mining system control unit based on the hydraulic power of that drilling rig
36 HPRC mining drill rods, each with six pipe resp. channels
HPRC mining head (in four different versions/configurations)
HPRC air inlet assembly
Because this assignment is a research and development project, the system has been under continuous supervision since it was brought into service in April 2009. With each completed drilling, AREVA and BAUER use the acquired knowledge to optimize processes, increasing productivity and gains per bore.
