Sommaire: The results being presented in this paper are those obtained during 1996 on a drilling automation project at Stobie mine. This project has successfully demonstrated that the remote operation of multiple drills (by a single driller) from surface using Tamrock Data Solo 1000 Sixty drillrigs is technically feasible and can potentially bring significant rewards in terms of productivity and work environment improvements, as well as labour and maintenance savings.

Sommaire: Recent advances in underground communications technology have demonstrated the feasibility of teleoperation and automation in underground metal mines. One major challenge lies in the automation of underground mobile machines from surface, with the potential to reduce significantly the need for human involvement in underground operations. This paper reviews the evolution of underground metal mining automation, principally related to the development of teleoperation and automation of mobile...

Sommaire: Automatic driving at high speed of an underground truck was tested at Brunswick mine in September 1995. Modifications to the truck included: a remote interface to control actuators, front and back video cameras to follow a roof mounted optical guide and proportional hydraulic controls on the steering.
The mathematical model of the hydraulic system was adjusted using least square regression. The steering data, used in calculating the regression parameters, were acquired from the moving truck....
