Design topics available

This page contains a hyperlinked list of pages that have been completed as part of Mine 448 - underground mine design project. Each topic has been completed as part of the course requirements for the design groups. It is hoped that with time, these guides will accumulate into a useful resource for the course. Comments on any of these topics can be left in the discussion page attached to each topic page.
