    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

  • A fuzzy method for selecting underground coal mining

    One of the crucial decisions affecting productivity of the mine is the mining method selection. Longwall mining is quite common in underground coal mining, and it allows the use of mechanization. As application of mechanization increases, production also increases and the number of workers decreases. Thus, the organization of work is easier, and the number of accidents decreases in the mine.

  • Mining method selection by multiple criteria decision

    Mining method selection is one of the most critical and problematic activities of mining engineering. The ultimate goals of mining method selection are to maximize company profit, maximize recovery of the mineral resources and provide a safe environment for the miners by selecting the method with the least problems among the feasible alternatives. Selection of an appropriate mining method is a

  • Underground mining method selection by decision making

    01.03.2009· Hartman (1987) developed a selection chart based on the geometry of the deposit and the ground conditions of the ore zone for selecting mining method. Miller-Tait et al. (1995) modified the Nicholas’ system and developed the UBC mining method selection process. 2.2. Studies on decision making techniques in mining

  • Factors influencing mining method selection

    Underground mining methods are the focus of this article. The selection of a mining method for an ore deposit is based on many factors that are driven by the economics and profitability of the mine for a company. These include the following: Ore grade and recovery; Cost of infrastructure; Ore extraction ; Labour and machine costs; Underground support costs; Geotechnical factors; Retrieved from

  • Surface Mining Methods and Equipment EOLSS

    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 method can be used for both hard rock mining of metal ore and coal mining in soft rock. In both cases, the method maintains continuous behaviour in the far-field rock. An orebody must be dipping less than 20° and have a relatively uniform grade distribution. Additionally, any displacement along a fault must be less than the thickness of the orebody. In hard rock mining, longwall mining
