Calculation of reserve estimation in the new pit design using mining software at PT. Tanjung Alam Jaya pit x, Banjar, South Borneo.

The mining planning and design were carried out in PT. Tanjung Alam Jaya, a coal company South Kalimantan. intends to re-mine the Pit X area requires comprehensive mine approach achieve its objectives. study focuses on long-term planning, specifically optimizing pit while considering company's specified stripping ratio limit calculating potential reserve volumes. research aims develop an optimized estimate quantity of mineable reserves based optimization results. findings include layout drawing calculated that can be extracted from design. excavation spans 38.1 hectares, with limits reaching depth -56 meters above sea level. shape extends northeast southwest, length 1,065 variable width 310 460 meters. features slope height 10 single angle 65 degrees. Moreover, haul road measures 21 10% grade. indicates total 1,400,263.48 tons across all seams. Additionally, it reveals 21,565,312.42 bcm overburden / interburden must stripped, resulting 15.40 for specific In conclusion, this demonstrates PT Jaya's efforts optimize their re-mining area. provides valuable insights through approach, aiding achieving objectives adhering limits.
