This study of the general mengambaran thickness conditions in the study area, counting the coal reserves in the area of research until the pit design and mine layout. From the correlation between the point of drilling. Resource calculation performed using software Minescape and the method of poligons. Volume obtained for the pit reserve of 12 hectares amounted 26900.01 tons and the amount of overburden to be opened for 78177.11 tons. With striping ratio is 1: 2.906.
