Abstract
Study of excavability criterion has been derived from empirical methods based on the specific condition of materials. This study aimed to evaluate excavatability criterions based on standarad metohods such as Franklin et al., 1971; Pettifer and Fookes, 1994;, and Equipment Handbook (Caterpillar and Komatsu). This study was undertaken through data collection on a similar geological condition on underdevelopment coal mining site. Sedimentary rocks formation, such as calystone, sandstone, and siltstone were the main rock-type investigated in this study. The parameters observed were Point Load Index (PLI), Fracture Index (FI), Unconfined Compressive Strength (UCS), and seismich velocity. The prameters were obtained from field testing and laboratory testing according to ASTM and ISRM standard. The investigatend materials had a maximum value of PLI, UCS, and seismic velocity of 0.55 Mpa, 15.75 Mpa, and 2803 m/s, respecitively. The evaluation of the predicition methods in this study undertaken by looking at the correlation of the selected prameters on the same set of samples. This study is continued on further study to provide more solid evaluation criterions.
