Abstract
PT. Freeport Indonesia is one of the first mining companies in Indonesia to engage in world-class copper, gold and silver mining, located in Tembagapura, Regency Mimika, Papua Province. The company PT. Freeport Indonesia in its operations uses an open mining system (Surface Mining) and underground mining (Underground Mining). Grasberg block cave underground mine is one of the future mines of PT. The Freeport Indonesia mine has ore reserves of 874 billion tons with a copper content of 1.04%, gold 0.81 gram / tonne and silver 2.9 grams / tonne and to extract these ore reserves the Grasberg Block Cave underground mine applies the block cave method. (collapsed) but since the opening of the Grasberg Block Cave mine in 2008 until now the mine is still in the development stage. Basically, this increase in production can be achieved in two ways, firstly it can be done by maximizing the productivity of the existing R1700 LHD (Load Haul Dump) tool, and the second way that can be done is by using the addition of heavy equipment and production support tools so that production capacity to be bigger. With such a situation, it is necessary to study the calculation of productivity or the addition of the GBC (Grasberg Block Cave) underground mining equipment of PT. Freeport Indonesia, so that production can run evenly, smoothly and in accordance with the existing draworder.
