The history of coal mining dates back to over 400. million years ago. Coal mining started in Midlothian, ia (near. Richmond) in 1748. Coal machines were available in the 1880s. The oldest deepmine facility is the Tower. Colliery, located in the UK, in 1805. Surface mining was started in 1912. 3.
The performance chart shown in Figure is valid for these trucks. Capacity : • Struck, cubic yards • Heaped, 2:1, cubic yards • Net weight empty = lb • Payload = lb • Gross vehicle weight = lb f• The trucks will be loaded by a hydraulics hoe having a 3cy bucket Figure
1 % increase in moisture will reduce gross CV by about 1 %. Heat is also lost due to evaporation and superheating of moisture in coal during combustion. 1% moisture in the coal reduces the efficiency of boiler by %. The wet coal reduces generation, results in increase in the secondary fuel ( fuel oil ) consumption and the auxiliary consumption.

The results indicated that a homogeneous truck fleet consisting of five 789C trucks, combined with a 994K loader, is the most efficient fleet option and will produce 1455 t/h. The combined optimized effect of each identified KPI of production led to a tonnage improvement opportunity of 5421 t per shift.
Longwall shearers The coal is cut from the coal face by a machine called the shearer (power loader). This machine can weigh 75120 tonnes typically and comprises a main body, housing the electrical functions, the tractive motive units to move the shearer along the coalface and pumping units (to power both hydraulic and water functions).
