The mechanization of platinum group metal (PGM) underground reef mining in South Africa has posed a challenge to mining engineers for several
decades. This is primarily due to the shallow dip angles and narrow thickness (<1.1m) of the tabular orebodies mined, and the technical issues faced in developing reliable drilling, bolting and loading machines suitable for such hard-rock mining applications. Presently, mining is typically conducted using hand drills and scraper shovels. These methods, however, are intensive in terms of manual labor, and limited in terms of
productivity, and improved methods are desired. This paper will review the technical challenges faced by an OEM in developing a reliable, 4
tonne, low-profile LHD for narrow-reef PGM mining.
