Blasting company breaks new ground with inverse drop raising

摘要

Blasting solutions company AEL has partnered with EBJ Mining Construction to successfully execute mechanised, inverse box hole blasting at gold producer Harmony Gold's Elandsrand mine, which has resulted in increased safety and production on site. Inverse box hole blasting has traditionally been successfully used in platinum-mining. In conventional box hole development in gold-mining applications, an incline raise is used to create an orepass by manually drilling down the host rock to advance to the orebody.
