However - there is a way!
Download the 4x DWF files manually (via inspecting the HTML page source);
Then you can use them with Autodesk's free online-CAD viewer;
Requires a sign-up, but once you're in you can upload the DWF files and they work perfectly.
The "bends3d.dwf" file is of most interest here. You can clearly see the KC Northern shaft and QC North shaft deviate around an obstacle, originally thought to be the Grand gallery, but as you can see in the drawing, the deviation appears to be much more than required to clear the GG.
