Mine Surveyor - Mining Basics - Open Cut Coal

Coal Mining. Once coal has been uncovered by either an excavator or dragline, an excavator and truck combination are used to mine the coal. To ensure coal is mined optimally as well as accurate reconciliations, surveyors complete a pickup of both the top of the coal (roof) and once removed, the bottom of the coal (floor). Therefore it is ...

This survey was conducted to determine the magnitude of the methane emission and control problem in U.S. bituminous coal mines. The resultant data indicate that the emission rate for any given coalbed depends primarily on the coal production rate and on mine depth, as well as on the nature of the coalbed and the surrounding strata.
