Studying the Appropriate Underground Mining Methods in Sukari Gold Mine

This paper represents an attempt to study mining methods and development in the area of underground mining in Sukari gold mine. Detailed mining and rock mechanics data had been collected from Sukari gold mine to select the appropriate mining method for underground area. Underground mining methods have been studied to show that the selected mining method in SUKARI gold mine is suitable for the geology of the ore body, and hence proposed mining method could be taken into account. A brief background about Sukari gold mine is given and the used mining method in Sukari gold mine has been approved. Some of the suitable mining methods are discussed according to selection method and the most appropriate one is listed. Mining method selection was done by UBC method and Hartman flow chart.

MSAHP: An approach to mining method selection

SYNOPSIS Mining method selection is the most fundamental activity of a mining study, because everything else depends on it. It is a process whereby the mining method attributes are matched to the orebody characteristics. This crucial decision must invariably be made at a stage of the study when the least information is available. Method selection with Analytic Hierarchy Process (MSAHP) is based on the Analytic Hierarchy Process (AHP) and was developed in Microsoft Excel™. It was designed to facilitate good decisions based on expert judgement and sparse data according to a systematic mathematical process. The program matches the attributes of 10 mining methods to the characteristics of the orebody under review and results in the ranking of the mining methods according to their suitability to the orebody. The underlying premise of MSAHP is that the mining method best suited to the orebody will also be the most economical. Keywords: mining method selection, orebody characteristics, Analytic Hierarchy Process.
