Technical paper: Grouting with the MPSP Method at Kidd Creek Mines, Ontario

By D A Bruce, vice president, Nicholson Construction of America and and F Kord, Kidd Creek Mines. This paper was first published in GE’s October 1991 issue.


One of the decade’s few advances in the methodology of rock grouting is the multiple packer sleeved pipe system. MPSP overcomes the problems posed to efficient treatment in the face of collapsing, voided or highly variable ground conditions. The method has been used with distinction to form grout curtains in association with several high dams in Asia and Europe, while it can also be used to improve the mechanical properties of masses when used in ‘consolidation’ grouting applications (Bruce and Gallavresi, 1988).

Most recently, it has been adpoted in an entirely different environment —to stabiilise highly variable weakly cemented rock fill, approximately 800m underground in an operational copper mine in northern Ontario. This particular case history is not only of interest and relevance to the underground engineering community, but it also provides a clear demonstration of the workings of the method in general. The program featured work in two distinct locations and phases, and the paper describes how observations from the first were used to optimise operational parameters in the second phase.
