Abstract This study shows the usefulness of borehole geophysical logging of density in the identification of coal seams, in relation to other lithologies present in a coal deposit located in the south of Brazil. Four drillholes were studied. The geol

The use of geophysical well logging data can help to solve problems related to the loss and absence of core samples in a coal deposit, providing extremely valuable information and at the same time reducing exploration cost. In this context, blast hol
