2020-5-1Open Pit Mining Open-pit mining techniques are rather simple and self-explanatory, excavate and relocate large quantities of waste rock and exploit mineral deposit at lowest possible cost. Open-pits are used when ore rocks are relatively shallow, and overburden surface material covering the deposit is relatively thin and not suitable for tunneling elements such as sand,.
