Abstract

Sebuku Tanjung Coal, a mining company, has a blasting location close tobuilding structures. This building is included in the Class 2 building on SNI 7571:2010 with a maximum peak vector sum (PVS) value of 3 mm/s or peak particle velocity (PPV) value of 3 - 7 mm/s at the frequency of 0-100 Hz. Several critical areas are located between 200 and 700 meters from the blasting location. The used initiation system is Hanwha Electronic Blasting System 2^nd Generation (HEBS II), which uses HiMex 70 (emulsion) as an explosive type. In this paper, the tie-up design of blasting uses segment and non-segment methods to compare the results of blasting using the two methods. Based on 16 compared data points, the vibration results obtained using segment and non-segment had a value range of 2,767-15,102 mm/s. The average result of the digging time using the segment method is 10.9 seconds, while the non-segment method takes 10.3 seconds. The average size of fragmentation (D80) with the segment method is 49.1 cm, while the non-segment method is 45.4 cm.
