Imagine you are a mining engineer tasked with overseeing the development design and excavation of an underground mining project in the Northern Limb of the Bushveld Complex in South Africa. The project is targeting mineralization containing palladium, platinum, rhodium, gold, nickel, and copper in the thick, high$-$grade, flat$-$lying, underground Flatreef deposit. The shaft is supposed to be sunk to a final depth of approximately $900$ meters $($m$)$ below the surface.

As the project lead, you need to plan the shaft sinking operation from scratch. This involves selecting the most appropriate sinking method, deciding on techniques for water control and shaft lining, and addressing all environmental and safety concerns. Your decisions should be informed by best practices and innovations in the field of mining engineering.
