OPEN PIT MINING THROUGH UNDERGROUND WORKINGSOPEN PIT MINING THROUGH UNDERGROUND WORKINGS INTRODUCTION A number of open pit mines in Western Australia (WA) are mining orebodies that have previously been mined by underground methods. There are hazards with high risk potential which develop where open pit mines approach and then progressively mine through underground workings.
