From 1981 to 1985, the Cyprus–Pla teau Mining Corporation mined a group of longwall panels in the central and northcentral portion of the study area. Other roomandpillar mining to the north of these panels occurred from 1989 to 1991, concurrent with the mining beneath the NFRF of .
degree of certainty. Coal quality cannot be controlled without some information about possible qualities of future mining blocks. The control of coal quality at the mine phase is usually planned from insitu coal parameters which are estimated from coal samples. These samples are commonly used to generate maps of insitu coal parameters.
