Mine Surveyor.net 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 usually a good practice to remove the overburden from above the coal prior to digging the coal. In some mines with large coal
