The selection of an optimal reclamation method is one of the most important factors in open-pit design and production planning.
It also affects economic considerations in open-pit design as a function of plan location and depth. Furthermore, the selection
is a complex multi-person, multi-criteria decision problem. The group decision-making process can be improved by applying
a systematic and logical approach to assess the priorities based on the inputs of several specialists from different functional
areas within the mine company. The analytical hierarchy process (AHP) can be very useful in involving several decision makers
with different conflicting objectives to arrive at a consensus decision. In this paper, the selection of an optimal reclamation
method using an AHP-based model was evaluated for coal production in an open-pit coal mine located at Seyitomer region in
Turkey. The use of the proposed model indicates that it can be applied to improve the group decision making in selecting a
reclamation method that satisfies optimal specifications. Also, it is found that the decision process is systematic and using
the proposed model can reduce the time taken to select a optimal method. 相似文献

Surface paste disposal method can be used to minimize environmental risks during storage of mine process tailings. There are some researches and industrial applications which prove success of the method. The surface paste disposal of mineral process tailings obtained from a Pb–Zn underground mine was simulated considering mine site conditions at laboratory scale in the study. The paste material was stored in the cabin/container layer by layer, and then, the cracks occurred after the paste formation of each layer were analyzed by image process. Meanwhile, leachate water collected from the bottom of the cabin was subjected to electrical conductivity (EC) analysis. Furthermore, the wetting–drying process was conducted to simulate the climatic conditions of the region. Additionally, some physical and geochemical parameters such as matric suction, volumetric water content, and oxygen consumption of the paste material were obtained using sensors displaced into different layers. The results of the crack analysis for each layer showed that the cracks intensity increased at lower layers. Moreover, the crack intensity and EC values of each layer showed a similar trend, and the crack intensity increased almost five times during the wetting–drying tests. The measured values of the parameters obtained from the tests indicated that the deposited paste material can be stabile during the deposition over the years under the climatic conditions of the region. 相似文献

Strategic mine planning includes different cut-off grade policy depending on economic parameters of mining projects and grade–tonnage
distribution of the deposit. Minimizing incorrect classification of ore and waste during grade–tonnage distribution is of
critical importance for a mining operation. This article reviews the influence of the ore grade–tonnage distribution over
the cut-off grade policy in a given mining operation. In this study, firstly, the interpolation parameters used to characterize
the grade–tonnage distribution in the orebody are given. The resulting distribution of ore and waste is used to analyze uncertainty,
risk impact, and to justify mine-planning decisions, according to the interpolation technique used and the number of geological
settings and sampling scenarios being considered. Then, the working scheme of the cut-off grade policy and economic parameters
are compared according to the resulting estimation from the inverse distance and the nearest neighbor methods. 相似文献
