overhand cut-and-fill mining

mining method

Quick Summary

Overhand cut-and-fill mining is an underground mining method used to extract ore. This technique involves removing ore in horizontal slices, starting from the lowest level and working upwards. After each slice of ore is extracted, the resulting void is filled, typically with waste material from the mineral processing plant. This fill material provides a stable base for mining the next slice of ore above. In this method, access raises are often constructed within the fill as mining progresses upward, serving functions like manways or ore passes. Alternatively, ore can be transported to an ore pass using load-haul-dump (LHD) equipment.1
