I suppose one could map both the spoil heap as a whole, as an area, and also the crest, as a line. The crest would be useful as a landmark, from a distance. The footprint of the spoil heap would be useful as a landmark, at close range. My impression is that no one would likely try climbing the

Currently in OSM we have two tags to describe some kind of slope that also get rendered in the mapnik chart and a couple of others: natural=cliff embankment (in the form man_made=embankment (feature) and embankment=yes (attribute)) Is this categorisation sufficient for any type of slope?
