Simple answer, plenty. Obvious choices would include: Masson, Wapping and Cumberland, Devonshire, Jug Hole, Old Ash, the mines of the Via Gellia (Ball Eye, Groaning Tor, Silver Eye, Slaley Sough, Dunsley Spring, Spinney Level, Old Gells, etc). I think though, the first three I have listed, would be a good starting point and all very close to Matlock.
