Abstract

PT. Newmont Nusa Tenggara (PT NNT), is a copper and gold ore mine
located in the Batu Hijau, West Sumbawa. In mining PT. Nemont Nusa Tenggara
drilling and blasting method for the process of the rock. The process of awarding
is done to relieve the parent rock of the rock, so as to facilitate the subsequent
mining process.
During this PT. Nemont Nusa Tenggara in analyzing the results of blasting
fragmentation in the field using only a split-desktop software using the shooting
method on the surface of detonation (Muckpile) by using two balls as objects of
comparison. The other method used is the kuz-ram models to predict blasting
fragmentation results before blasting activities take place.
In connection with it will be an assessment of the results of blasting
fragmentation using a split-desktop and model that Kuz-ram-ram Kuz later
models can be used to predict blasting fragmentation of the design geometry
imposed by the company.
Based on field observations of the model estimates the resulting
fragmentation Kuz-ram (Theoretically) greater than the results predicted splitdesktop
which is a result of direct observations in the field for each rock. The
level difference in size rock fragments resulting average model of kuz-ram for p20
in Diorite rocks of 11.65 cm, 27.22 cm for P50, P80 of 55.58 cm, and the top size
of 314.13 cm. On the rocks Vulkanic to p20 by 9.84 cm by 18.18 cm P50, P80 of
37.97 cm, and the top size of 231.19 cm. In Tonalite rocks to p20 by 8.08 cm,
12.65 cm for P50, P80 of 25.15 cm, and the top size of 151.69 cm.
