Selection of mining method

2019-6-28 · 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 METODOLOGY BY …

2019-4-25 · mining method based on the RMR system (rock mass rating). The first approach to a quantitative selection method is developed when David E. Nicholas (1981) with a numerical approach for the selection of extractive method (Selection Procedure - A Numerical Approach); in this method a scale is formulated for the weighting of each extraction method.

Selection of new appropriate mining method: case of ...

2019-8-18 · The selection of the adequate mining method is the cornerstone for mine planning and design. This selection depends on geological, geotechnical, economical, and environmental parameters. This paper''s main purpose is to select the most appropriate mining method for the south body of Boukhadra underground mine (NE Algeria). To do so, a new study is needed …

Optimal Selection of a Longwall Mining Method for a Thin ...

2016-7-14 · The selection of a mining method is one of the most important decisions made by mining engineers. An appropriate fully mechanized mining method is of great importance to mining design and capacity planning for thin coal seams. Therefore, the comprehensive evaluation of alternative mining methods is an important part of mining design. Several …

Mining method selection by multiple criteria decision ...

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 ...

Selection of overburden surface mining method in West ...

2017-10-2 · selection of the optimal mining method by AHP. Results of this research indicate that application of SM method would yield higher cost of overburden removal than conventional mining methods in rocks with a high unconfined compressive strength and abrasivity. A significant advantage of SM method, where applicable, is the elimination of the ...

12. Mining methods and method selection

2018-1-30 · 12.5 Mining method selection-The mining principles and methods have evolved to meet the geomechanical and operational problems of various cases.-Final choice of mining method will reflect both the engineering properties of the orebody and its setting, and the engineering attributes of the various methods such as mining scale, production rate ...

Mining method selection by multiple criteria decision ...

2009-8-26 · 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. The mining engineer must

Table 3 from A new approach to mining method selection ...

The main purpose of this paper is to represent a solution to the problem of mining method selection (MMS) in mining projects. To this aim, the well-known MMS technique of Nicholas has been modified so that in addition to eliminate its defects, it would be possible for mining engineers to easily assign their engineering judgments to unsteady and uncertain characteristics of …

Mining method selection and transition depth …

2021-5-5 · "mining method selection" and "determining transition depth from open-pit to underground mining" an accurate procedure is introduced step by step. First, it is essential to specify if an ore deposit potentially will have mined by athat combined method of open-pit and

The Use of Risk Analysis in the Selection of a Mining Method

The Use of Risk Analysis in the Selection of a Mining Method. It is very rare in the underground hard rock environment to find a deposit that is ideally suited to a specific mining method. Usually the irregular shape of the orebody will allow the deposit to be extracted by more than one mining method. During the prefeasibility stage, a number ...

Underground mining method selection by decision making ...

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.
