the past for mining method selection. Bajkonurov (1969), Budko (1971), Imenitov (1970) and Popov (1970) have suggested a procedure for mining method selection that comprises two phases (preliminary mining method selection and the selection of the most suitable mining method from a group of applicable methods). The selection of the
The selection of a suitable mining method for an ore deposit requires the consideration of a numerous criteria, such as mining-geological factors, economic factors and miningtechnical factors. This selection problem is based on the comparisons of mining method alternatives according to the identified criteria.
The selection of underground mining methods is primarily based on the geological/spatial setting of the deposit. Candidate methods can therefore be chosen and ranked based on estimated operational/capital costs, production rates, availability of labors and
Mining method selection is one of the most critical and problematic activities of mining engineering. The ultimate goals of mining method selection are maximizing company's profit and recovery of the mineral resources and providing a safe environment for the miners by selecting the suitable method with the fewest problems among the feasible ...
The mining engineer must balance the input parameters and select the method that appears to be the most suitable; mining method selection is both an art and a science.
mining method selection metodology by multiple criteria decision analysis - case study in colombian coal mining The purpose of this paper is to present an application of the AHP technique to a mining method selection problem faced by a Colombian mining company; in this case we use five decision makers.
The selection of the mining method is a complex task considering many technical, economic, human and historical factors. Analysing all these factors will assist in identifying the
METHOD SELECTION - STAGE 1 The main purpose of Stage 1 is to select those mining methods which should be considered in greater detail. The simplest way to do this is by defining those characteristics required for each mining method and then determining whether the characteristics of the deposit are suitable.
The feature selection methods are typically presented in three classes based on how they combine the selection algorithm and the model building. ...

Selection of mining method. Context: The selection of a mining method for a given orebody can be a challenging assignment and may need to address personal bias for or against a particular method.The selection of the mining method may also need to occur prior to the completion of desired geotechnical or ore value determinations.
Mining method selection by integrated AHP and … The AHP is used to analyze the structure of the mining method selection problem and to determine weights of the criteria, and PROMETHEE method is used to. Chat Online
This has caused the choice of underground mining method to be revised several times and the process to final mining method selection to take longer than usual. In order to achieve the planned production start-up date of July 1998 the process has been allowed to progress in parallel with development of the underground mine.
In this module, students are given an ore body deposit along with detailed geological and rock characteristics such as dip, depth, RMR, etc. Based on the characteristics, a list of suitable mining methods is displayed using UBC Mining Method Selection.

The Coal Mining Methods Selection of Large In order to select the reasonable coal mining method of large mine, analysing the main factors of affecting the mining method and establishing the ...
UBC Mining Method Selection (see Appendix II - Mining Method References) is a modified version of the Nicholas approach for selection of mining method based on orebody characteristice (refer Nicholas 1981). Selection involves summation and ranking of numerical values associated with orebody characteristics that reflect the suitability of a particular method.
Mining method selection by multiple criteria decision making tools by M.R. Bitarafan and M. Ataei* Synopsis Mining method selection is the first and most important problem in mine design. In this selection some of the parameters such as geological and geotechnical properties, economic parameters and geographical factors are involved.
