Open-pit gold mining is the process of mining by way of excavation which was made on the surface of the soil with the aim of finding gold mineral ores and worked for the mine life. In the exposing stage and the process of mineral ore mine in open-pit gold mining, is generally carried out in the gold mining industry on a large scale which required the excavation process and move the rocks in large quantities. In the mining industry, gold obtained by isolating it from rock gold ore (extraction). According to Greenwood et al (1989), rock gold ore decent to be exploited as the gold mining industry, gold content of approximately 25 g / tonne (25 ppm).
Open-pit gold mining the have main objective of the commercial value and open mining operations undertaken with the value of the lowest possible cost in the exploitation of mineral deposits and generate maximum profit. Planning, Selection of the physical design parameters of open pit mining, scheduling program for the extraction of mineral ores is an important stage in the open-pit gold mining.
