The continuous miners cut and load the coal into shuttle cars, which haul and empty the coal onto a belt conveyor system leading to a coal stockpile on the surface.
Coal mining Coal mining Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities ...
Continuous miner: remotecontrolled machine with a large rotating steel drum equipped with tungsten carbide teeth that scrapes coal from the seam. Production time: production unit of a mine, where coal is mined Shuttle car: electric powered vehicle with a capacity of 20 tons used to transport coal from a mined seam to a section conveyor belt.
equipment, primarily for coal mines. These coal mine chapters include continuous miners and longwalls, including bleeders. Coal seam degasification is covered extensively. Other coal mine chapters deal with methane emission forecasting and predicting the excess gas from troublesome geologic features like faults.
On a "walk between" super section, one miner operates at a time. Each miner operator stays with his or her continuous mining machine, and while the other continuous mining machine is mining coal, the first machine changes working places, services the machine, assists with face ventilation adjustments, and prepares to mine the next cut of coal.
