productivity. In surface mining applications, the ESP addresses the selection of equipment to extract and haul mined material, including both waste and ore, over the lifetime of the mining pit. In this paper, we focus speci cally on the truck and loader equipment selection problem for surface mines.

In subsequent studies a classification system divides underground mining into three groups based on ground conditions assigning each type of support required (Morrison, 1976). (Laubscher, 1981) proposes a selection methodology for underground mining method based on the RMR system (rock mass rating).
Mining method selection is a critical point and a strategic issue in the mining engineering process. Selection of a method unsuitable for deposit characteristics may make exploitation of the orebody troublesome and sometimes uneconomical. So, available deposits should be evaluated carefully in an optimum manner. In the process, the selection of ...

Coal mining - Coal mining - Choosing a mining method: 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 …

In underground mining a hoist or winder is used to raise and lower conveyances within the mine shaft.Modern hoists are normally powered using electric motors, historically with direct current drives utilizing Ward Leonard control machines and later solid-state converters (), however modern large hoists use alternating current drives that are variable frequency controlled.
2.1. Studies on mining method selection. 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.
phical data, availability of degasiﬁcation systems, type of degasiﬁcation system, sulfur content and caloriﬁc value of mined coals, annual coal productions, and emissions from ventilation systems. Mining parameters and mine characteristics are im portant for degasiﬁcation system selection since they can affect methane emissions.
Choosing a Data Mining System. The selection of a data mining system depends on the following features − Data Types − The data mining system may handle formatted text, record-based data, and relational data. The data could also be in ASCII text, relational database data or data warehouse data.
mining equipments selection. This system is able to involve the expert knowledge in primary and secondary selection of equipment for surface coal mines . In 1990, another expert system, in order to classify equipment, was planned in the open pit coal mine of Britain with the help of fuzzy logic.
Notes on Mining Method Selection. UBC Mining Method Selection 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.
Recommendation: There should be renewed support for advanced coal mining and processing research and development to optimize use of the nation's coal resources by increasing the amount of coal that is economically minable through technological advances that …

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.
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.
The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use. New technologies can benefit the mining industry and consumers in all stages of this life cycle. This report does not include downstream processing, such as smelting of ...
Water management in mining: a selection of case studies F o r e w o r d Water is a fundamental resource for life. Whether from groundwater or surface water sources, availability of and access to water that meets quality and quantity requirements, is a critical need across the world. We all share responsibility for meeting this need now and in ...
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 the ...
Jun 19, 2018· Data mining of the information stored in databases could provide insights into disease states and how best to manage them. For years, research has been done to show the value of Clinical Information Systems, and these have highlighted not just the benefits but also the barriers that might be faced by hospitals who implement such systems.
