Research and Practice of Goaf Management of An Open-Pit to Underground Iron Mine

Abstract

In view of the local surface cracks and collapse in the collapse area of an open-pit underground iron mine, considering the safety and thoroughness of the goaf treatment, the scheme adopts the caving surrounding rock method to control the goaf area, and the implementation of this plan eliminates the high and steep slopes to form stable steps, effectively treats the goaf area while fully recovering mineral resources, and provides a guarantee for the sustainable development of the mine.
