In open-pit coal mines, the haul units for overburden material are usually large, off-highway, end-dumping trucks; their capacities range from 35 to 250 tons. The stripping shovel has a large bucket, usually sits in the pit on the top of the coal seam, digs into the overburden material, and deposits it in the adjacent mined-out area.

Classification of Underground Mining Methods Mineral production in which all extracting operations are conducted beneath the ground
Surface mining, which can be used when ore is close to the earth's surface, is an older and more pro-ductive method than underground mining. Open-pit mines differ depending on the nature of the mate-rial removed. Shallow mines from which gravel and sand are extracted are generally referred to as quar-ries; deeper, long mines from which coal ...
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.

EQUIPMENT SELECTION b) Face Supports. While it is frequently argued (correctly) that all items on a longwall face have to be considered as parts of an integrated unit and be fully compatible, it cannot be denied that poorly designed and inadequate roof supports are likely to have a greater effect on results than other items, and to that extent are more important.
Some of the biggest developments have been in size and power, largely associated with high production mines in thick seams. Shearers weighing up to 100 tonnes supplying 1 MW of power to the ranging arms are now in use with increases in the size of shearer haulage equipment .
Equipment selection for high selective excavation surface coal mining by H. Aykul*, E. Yalcın†, I.G. Ediz*, D.W. Dixon-Hardy‡, and H. Akcakoca* Synopsis The choice of which mining method to use at many large surface coal mines is often dicated by what machinery is available or what experience the mine management can offer. One of the most
The Mining Method selection problem focuses on choosing the correct excavation method for the given mining conditions. Generally, this research is based on anecdotal methods, where a feasible solution is sought, rather than an optimal solution. Much of the literature on mining method selection does not discuss equipment selection modelling in
underground coal mine and electrical equipment and electrical installations on the surface directly associated with the underground operations of a coal mine. This standard does not apply to the general surface of an underground coal mine.

Underground mining operations around the world pose similar risks to worker safety and health. Though different techniques are used to extract base metals, precious metals, nonmetallic minerals, diamonds and coal, the hazards do not differ that much. The deeper the mine, however, the greater the risk. Safety Challenges in Underground Mines
