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.
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 technological, economic, and social factors.

Underground coal mining is one of the oldest forms of mining. This type of underground mining took a lot of planning, where tunnels were built to and from ventilation shafts and rail shafts to allow for transporting coal with belt conveyor. While in the past, underground mining was done by pick-and-axe extraction, the continuous miner and other ...

station. The coal seems at SLE contain bands of ash which under normal mining conditions are extracted with the coal. This increases the ash content of the run of mine coal and results in lower efficiency at the power station and financial penalties for SLE. In this paper, therefore, selection of the best possible equipment
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.

FIGURE F-1 Schematic of a room-and-pillar coal mine section. SOURCE: Arch Coal, Inc., 2012. FIGURE F-2 Details of the longwall face. SOURCE: EIA, 1995. There are several variations of each method. However, ever since the introduction of continuous miners in the late 1940s, room-and-pillar continuous mining has been gaining ground over conventional room-and-pillar mining.
Underground mine performance in coal and mineral industry is declining and needs high productive systems. In fact the world scenario of underground production is dismal and many companies are facing closure even in USA. Proper selection of mechanization equipment requires many factors to be
concentrations during overburden drilling in surface coal mining operations. 8.3.2 Ventilation Underground coal mines are required to be mechanically ventilated [30 CFR 75.300-75.3301. The purpose of mechanical ventilation is to provide fresh air to the underground miners and to carry off toxic and explosive gases and dusts.
This feasibility prototype can be deepened by adding modules for other equipment groups for underground coal mines and can be broadened by adding modules for surface coal mining and hard rock ore mining. Because equipment selection is an important component of mine planning and design, the availability of a knowledge-based system for equipment ...
