Integrated Site Investigation Method to Analyze Subsurface Condition for the Belt Conveyor

The unstable slope is one of the main problems which cause instability of the mining industry facilities, especially when a s lope has a belt conveyor built on it. This problem generally will affect the mine operation. The unstable slope in the surrounding of the belt conveyor route is related with mining production. Therefore, the integrated investigation must be conduct to obtain subsurface information and to analyze the slope stability along the belt conveyor route.The purpose of this research is to analyze subsurface information by using an integrated investigation which consists of elec trical resistivity tomography, self potential, cone penetration test, test pit, and geological engineering mapping. All of those investigations are used to produce a representative subsurface model.
