Selection of the mining method is one of the most important decisions in mine development. Open pit, underground methods or both of them are selected depending on the geometry properties of the deposit, its position with respect to the surface and so on [3].
(2008) have used the AHP approach for mining method selection. Otherwise, Bitarafan and Ataei (2004) have used different fuzzy methods as an innovative tool for criteria aggregation in mining decision problems. Also, Alpay and Yavuz (2009) have suggested a combination of AHP and fuzzy logic methods for underground mining method selection.
Underground mining method selection is one of the most important decisions that mining engineers have to make. Choosing a suitable underground mining method to extract a mineral deposit is very ...
The selection of an underground mining method using the fuzzy topsis method. 163 nature, and humanity and facilitators for common sense reasoning in decision making in the absence of complete and precise information (Bojadziev & Bojadziev, 1998).
appropriate mining method is selected based on technical, economic, and environmentally accountable considerations. The first step in selecting the most appropriate mining method is to compare the economic efficiency of extraction of the deposit by surface and underground mining methods . This section reviews surface mining methods and ...
Underground mining is carried out when the rocks, minerals, or precious stones are located at a distance far beneath the ground to be extracted with surface mining. To facilitate the minerals to be taken out of the mine, the miners construct underground rooms to work in.

May 17, 2017· The aim of this paper is to represent the solution to the problem of selecting suitable underground mining method for the mining industry. It is achieved by using two multi-attribute decision making techniques. These two techniques are weighted product method (WPM) and preference ranking organization method for enrichment evaluation (PROMETHEE).
The equipment selection process for an underground mine design plan has an extremely wide scope as there are a myriad of parameters to consider when incorporating mobile and stationary equipment in hard or soft rock mining applications. This article primarily focuses on the initial selection of mobile equipment in hard rock mining operations.
As has been the case since the early Phoenician traders, the minerals used by modern man come from deposits scattered around the globe. The price received is more and more being set by worldwide supply and demand. Thus the price component in the profit equation: Profits = Material sold (units)x(Price/unit – Cost/unit) is largely determined...
Underground mining method selection is one of the most important decisions that mining engineers have to make. Choosing a suitable underground mining method to extract a mineral deposit is very important in terms of economics, safety and productivity of mining operations.
Jul 21, 2016· Underground mining is the process of extracting minerals and ores that are located too far underground to be mined efficiently using surface mining methods. The primary objective of underground mining is to extract ore safely and economically while minimizing handling of waste rock. Typically, underground mine has less environmental impact.
As a global SRK group, we have specialist underground mining expertise to provide solutions for the unique features of each project. Based on this extensive experience, we utilise an innovative and rigorous mining method selection and planning methodology that maximises the economic benefit of the project.
Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on .

First phase is the mining method selection on technical suitability to the orebody; for which two methods are. The UBC method is applied first resulting in the selection of the area of sublevel stoping methods. Later a new technique is introduced to optimize the mining method selection process and to control the wide spectrum of mineral deposits.
