Mine Mules: ˜eir Use in Coal Mines in the United States
Getting coal to the surface was, and still is, the ˚rst move toward its ˚nal destination. In the era before World War II, it was transported to the surface in massive quantities almost exclusively in coal cars. From the beginning of the industrial revolution, many methods were used to remove coal cars from mines, among them the "mine mule."

Coal Mines in Europe - A Reality We Still Need to Accept
A Reality We Still Need to Accept. Coal mines are not just images from 'Germinal', Émile Zola's famous novel. Although doomed to disappear due to the catastrophic impact on the environment, coal mines remain a reality in many European countries. However, coal accounts for only 15% of European Union's energy production.
Machines Used in Coal Mining - Career Trend
Conventional Mining. Conventional mining employs crews of miners who use explosives and drills to extract coal, which is then loaded onto cars for transport to the surface. This method presents higher risks to miners because of the explosives. The coal dust generated by the drilling and explosives is also a health hazard when continuously inhaled.

Researchers also measured the levels of vehicle jarring/jolting. Four basic seat designs were compared on low- and mid-coal seam shuttle cars during production operations at two underground coal mines. Two seats were currently used on the shuttle cars; another two were NIOSH designs.
Underground Mining Transportation & Haulage Systems
Mechanical haulage in metal mines is of four general types: (1) Locomotive, (2) scraper or slusher, (3) rope, and (4) belt conveyor. Locomotives for underground use are powered by electric, compressed-air, or, rarely, gasoline motors. Diesel locomotives have been used extensively in Europe, but have not been adopted in the United States.

Coal Mining: How Is Coal Mined? - Science ABC
Surface mining and underground mining are the two major schools of coal mining. To qualify for surface mining, the coal deposits must be within 50-80 meters of the surface. The job of a miner primarily involves removing 'overburden'— rock, soil, trees etc. – that mix with the coal deposits and cover them near the earth's surface.

Abstract. Although free steered vehicles (FSCs) on rubber tyres, especially the diesel-engined load-haul-dump (LHD) and utility types, have dominated methods at metal and industrial mineral operation for a 2 decades, it was not until the late 1960's that the first trials were conducted in coal mines. The main reason for the long development ...
Coal Miners - West ia
Coal mining is a dangerous job requiring skill and judgment. In the hand-loading era, an underground miner's workplace, usually called a "room," was only as high as the coal seam. A room in the Pocahontas seam could be more than 10 feet high, while workplaces in the Kanawha and New River seams often were no taller than four feet.

Mine Car Theory
Mine Car Theory. Size: The size of mine cars may be determined by the physical conditions of the mine. Low-coal seams demand low height cars. Poor roof requiring timbering close to the track will often limit the width of the cars. The radius of the smallest curve will limit the length of the car. In low-coal mines, large capacity is obtained by ...
