I have to contradict in one point. I know of a lot of former and present 
quarries where the faces are inclined 90° and ten'ths of meters high. 
Maybe this is not so much the point for open pit mines. But tagging 
should be ready to cope with non-natural steep faces. I see no problem 
however in using some man_made key for this. "embankment" might be 
misleading, however. What about man_made=cliff for non-natural steep drops?

The renderer then could decide whether to choose differentiating 
drawing. (Most probably he won't do so).
