  • 6.3.5 Indicative Project Schedule Mining Would Be Staged To
    AECOM Rix's Creek Mine - Continuation of Mining Project 42 Environmental Impact Statement – Rix's Creek Mine - Continuation of Mining Project 6.3.5 Indicative Project Schedule Mining would be staged to maximise recovery of coal, whilst enabling the progression of rehabilitation as soon as practicable following the completion of mining and achievement of desired landform levels. Rehabilitation of the site to final landform would be completed in accordance with the Rehabilitation Strategy. The timing of key project elements is as follows: - Expand West Pit commencing from 2016 through to approximately 2037 to enable extraction of the resource; - Commence construction of the cut and cover tunnel no later than Q4 2018; - Increase in production to approximately 4.5Mtpa ROM coinciding with closure of Bloomfield Mine; - Progressive rehabilitation of the site with the expansion of the West Pit; - Establish entry location for the underground resource (southern end of the North pit); and - Mine closure preparation from approximately 2035 until the end of the Project (refer Section 25.0). This timing is indicative and may change due to economic or other factors. 6.3.6 Plant and Equipment Plant and equipment currently used by the Mine is detailed in Table 6-1.

  • A Decision Support System for Optimal Equipment Selection in Open Pit Mining: Analytical Hierarchy Process
    østanbul Üniv. Müh. Fak.

ABSTRACT : This study has been directed to the research of an optimal loading-hauling system in an open pit mine. There are many factors that affect the equipment selection processes. These factors are both qualitative and quantitative according to structure of the selection. Decision-makers need a decision support system that evaluate the factors in a complex structure for optimal decision making. In this paper, Analytical Hierarchy Process (AHP) is used for equipment selection in open pit mining. For this purpose, this study involves with the selection of an optimal loading-hauling system from mine to a power station to be established in an open pit coal mine located Orhaneli, western part of Turkey. The optimum alternative has been found as shovel-in-pit crusher-belt conveyor, consequently. Keywords : Equipment selection, decision making, multiple attribute decision making, analytical hierarchy process ÖZ : Bu çalÕúma, açÕ k ocak madencili÷inde optimum yükleme-taúÕma sisteminin seçimine yöneliktir.
