Mining methods and method selection 12.1 Mining excavations Recovery of mineral from subsurface rock involves the development of physical access to the mineralized zone, liberation of the ore from the enclos ing host rock and transport of this material to the mine surface. Excavations of various shapes, sizes, orientations and duty functions ...
The problem of production method selection in surface or underground mining has been studied by many researchers using the AHP (Karadogan et al. 2001;Mohsen et al. 2009;Alpay and Yavuz 2009;Azadeh ...
Nieto (2010) developed a selection method based on defined field key deposit indicators (KDI) and comparing them to the KDIs that are favorable to a series of mining methods considered.
The problem of underground mining method selection has been studied in the literature. Boshkov and Wright (1973) proposed a classification system which was one of the first qualitative classification schemes. Morrison (1976) suggested a selection chart for mining method selection. Laubscher (1981) proposed a selection methodology of an appropriate mass …
Mining method selection is a process whereby the mining method attributes are matched to the orebody characteristics. The mining method whose attributes most closely match the orebody …
Principles of the selection of mining method are as follows: (1) safe production; (2) high recovery rate, low dilution rate of ore, and full recovery of resources; (3) simple stope structures as well as mature and reliable mining techniques; (4) small amount of work for stoping development and …
Mining Method Selection (MMS) is one of the important decisions in the mining design. The appropriate decision guarantees economic exploitation and an unsuitable selection may lead to mining losses. ... Selection of overburden surface mining method in West ia by analytical hierarchy process, 1 (2014), pp. 306-314, 10.1007/s40789-014-0019 ...
Section 1 presents an overview of surface mining methods and practices as commonly employed in modern surface mining operations. The description includes a comparison of the …
Additionally, the operational parameters of the mining equipment ought to be considered. In this study, a universal set of evaluation criteria has been developed, and an evaluation method has been applied for the selection of surface mining equipment and the processing system to be operated in specific mining conditions, defined by the user.
the selection of excavation methods and equipm ent is more complex for surface mining than for underground mining. In surface mining, blasting patterns have to be properly planned to
The main mining methods may be briefly classified as Strip Mining, Terrace Mining, and the Conical Pit Mining (next section). 8.1.1 Strip Mining There are two main categories. 8.1.1.1 …
These factors are decisive for the selection of suitable engineering facilities, the order and possibilities of surface mining work. ... The on-slope-deep method of surface mining combines the characteristic features of the 2nd and 3rd kind. The kinds of deposits (with flat-land relief) suitable for surface mining, ...
The purpose of this chapter is to gain a better understanding of the different underground scenarios in terms of mining methods, layouts and associated excavation geometries.
The most crucial event in a mining project is the selection of an appropriate mining method (MMS). ... and an evaluation method has been applied for the selection of surface mining equipment and ...
INTRODUCTION The selection of mass mining methods is the situation facing not only planners of new operations, but also those involved with cur- rent operations, including the eventual change from open-pit to underground. Increasing ground control problems on many mines, plus a better understanding of dilution and ore loss problems have meant a review of current mining …

The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic, and …
In this study, a universal set of evaluation criteria has been developed, and an evaluation method has been applied for the selection of surface mining equipment and the processing system to be ...
The selection of the mining method is one of the most crucial decisions in the design stage of mine that mining engineers have to make. Selecting a mining method for mineral resources is completely dependent on the uncertain geometrical and geological characteristics of the resource. ... Comparison of Surface Mining Methods; Summary; Preview ...
Selection of the most optimal method of mining in the stage of designing the mine is considered to be an important and sensitive issue as far as designing the system of exploitation of a mine is concerned. This selection is based on geological, geotechnical, geographical, economic, social and political studies, etc. recognizing all of the factors that impact the method …
First, a rational selection of the four best-ranked mining methods for underground mining is performed using numerical methods (Nicholas' approach and the modified approach of Nicholas, i.e., UBC ...
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 practices. 1.1. Classification of Surface Mining Methods Extraction of mineral or energy resources by operations exclusively involving personnel
There are 5 main types of surface mining, which are used in various degrees and for different resources. These mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource.
The optimal mining method has the highest priority percentage. The results of these adjustments for the cost criteria can be seen in Table 8. Results show that the optimal mining method selection continues to be the SM mining method until the of cost priority percentage is increased by approximately 20 %.
Key words : Equipment Selection, Surface Mining, Shovel-Truck Productivity, Mining Method Selection, Multi-Commodity Network Flow Introduction The general Equipment Selection Problem (ESP) is to choose a collection of compatible, but not necessarily homogeneous, items of equipment to perform a specified task. ... Mining method selection by ...
Different mining methods are designed to produce different types and magnitudes of displacements, in the near-field and far-field domains of an orebody. For example, the …
Under similar conditions, surface mining is generally regarded to be more advantageous than underground mining. In the selection between surface and underground exploitation methods, there are a ...
The mining method selection for underground mining can be described as a multi-criteria decision-making process, as several factors are involved in the selection process.
