| dc.description.abstract | ABSTRACT
The optimum vibrations generated from the delay, distance, and explosive settings on the
destruction of the ground cover or OB can accumulate the effect of the damage. Research was
purposed to view the process of coal blasting and the impact of distance and explosives the
detonation process. The data used in the research is a secondary force of distance, explosives,
drilling patterm (7 m burden and 8 m distance) and blasting pattern (staggered patten/zigzag).Data
are
prepared using Microsoft Excel by inserting distance and explosives materials
and for PPV value. PPV value is compared with the distance value (scaled distance). The result
of research shows the process of blasting using a zig-zag system with distance between 7 m
and spacing 8m, depth of 3 m - 14m. Explosived material content (ANFO) with averaged
101.74. The impact of the distance and the explosives materials from PPV calculations is not
very significantly indicated by the PPV value of 3,62 mm/s | en_US |
