Wikipedia, an adit is "entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level." Above is a nice example, which, sadly, is no longer open to explore. In the diagram below, I've sketched out (from memory) the rough layout of the mine. The diagonal checks indicate areas of particularly intense brecciation- though all the host rock has been through multiple episodes of shattering and recementation. The breccia zones are exaggerated in width for clarity and continuity- the width of the addits more accurately represents the brecciated zones.
