What is Geometri Peledakan dan Rumus Terkait about?

This document discusses parameters for explosive loading geometry in rock blasting. It describes key geometric factors such as the diameter of blast holes, burden, spacing, and how they affect the blast results and fragmentation. The optimal diameter depends on factors like the rock characteristics and desired fragmentation level. Burden is the shortest distance from the blast hole to the free face, and is usually 25-40 times the hole diameter. Spacing is the distance between adjacent blast holes in a row,
