Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit ...
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.

and equipment selection in coal mines. Ash and sulfur values are important factors in the selection of the appropriate coal portions considered for coke production. However, the materials are important for environmental control of coal mining [1]. Iranian coking coal reserves/resources are between 7-10 Gt.
Coal Mining in South Africa. Coal mining's advent in South Africa can best be traced to the start of gold mining in the late 19 th century, particularly on the Witwatersrand, with the first coal in appreciable tonnages being extracted on the Highveld coal field close to the nascent Witwatersrand gold mines. However, demand began to grow ...

Mechanized mining technical process (MMTP) related to the control method of the shearer is a vital process in thin coal seam mining operations. An appropriate MMTP is closely related to safety, productivity, labour intensity, and efficiency. Hence, the evaluation of alternative MMTP is an important part of the mining design. Several parameters should be considered in MMTP evaluation, so the ...

A new approach for prediction of face advance rete (FAR) prior to mining operation and determination of the operation efficiency after mining operation in retreat longwall mining panel is presented based upon the concepts of rock engineering system (RES). For this purpose, six longwall panels considered in Parvadeh-I coal mine. Seven major effective parameters on FAR was selected …
Mining is one of the most vital components of modern society due to the use of mined minerals in almost every consumer product. Additionally, 50% of the nation's energy comes from coal or nuclear power that uses uranium. To support this need for modern equipment, mines are found in all 50 states, including our home state of Nevada.
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.
