ABSTRACT
This paper briefly outlines the underground mine design changes being presently trialled at the Silver & Baryte Ores Mining Co., Bauxite Operation. The trials are predominantly targeting steeply inclined, 20 to 30 degrees, bauxite orebodies with a thickness exceeding 8 metres. The changes include how the ore-body is accessed, the location and orientation of ore drifts, the extraction method and extraction sequence. The mining method currently used in these types of deposits, is a combination of room and pillar with cut and fill. This mining method has been in practice at the Bauxite Operation for several decades. This paper explores the benefits of this method, as experienced by the mining operation, and then outlines the changes being trialled to overcome any shortcomings. The final results from the trials will be available by October 2000.
