| Summary: | <p>Abstrack:<p align="justify"> The geology of K area is characterized by the existence of normal faults, anticline, and igneous intrusion. Data from borehole give a better interpretation of such geological structure.<p align="justify"> The geological Condition of the area plays an important role in pit planning. Considering the faults and anticline, the area is devided into 3 mining blocks. In each block, the potential is then defined taking into account the technical aspects such as geotechnics<p align="justify"> . <br />
The result of reserve estimation for 3 blocks in K area by using cross-section method indicates that the proven coal reserve is 5,152 227 tons while the mineable coal reserve is 4,788,893 tons. For mineable coal reserve, it is indicated that the stripped overburden is 23,695,046 bcm with the stripping ratio of 4,9 bcm/tons. |
