Fire-retardant materials have also been developed for other applications in mines such as ventilation ducting, brattice
cloth (sheets used for ventilation control) and cables.
This work involves the removal of cementitious material along the main shaft, as well as installation of a metal brattice
between the east and west halves of the shaft, repairing shaft steel, and installation of a new power cable, along with additional work, which is expected to improve the shaft's functionality and possibly improve its hoisting capacity.
In addition, the plan includes removal of unused utilities, construction of a water ring to prevent ice from forming in the winter, the installation of a metal brattice
between the east and west half of the shaft providing a physical barrier between the two halves, repair shaft steel, and installation of a new power cable; all of which should improve the shaft's functionality and possibly its hoisting capacity.
