The ABM Group of companies delivered an all-encompassing, end-to-end solution for Coronado’s Mammoth Underground Mine, expertly guiding the project from its inception through to operational readiness. This turnkey approach was evident in the highwall stabilisation across the four portals, where ABM developed and executed a robust stabilisation strategy. This strategy included long tendon support, meticulous mesh draping, and the precise application of shotcrete for each portal before the drift excavations.
