Study of Weathering and Rock Mass Quality using the Geological Strength Index (GSI) method on the Tuntun mine road Banggai Regency Central Sulawesi Province

Abstract

Abstract The mining road in the Tuntun area of Banggai Regency, Central Sulawesi Province has experienced a landslide. The mining road mitigation engineering is a concern for the sustainability of road use. The study area is composed of peridotite rocks which are included in the Ophiolite (Ku) rock formation, where these rocks undergo a very strong deformation process by showing the fractured rock conditions. The Study of Weathering and Rock Mass Quality Using the Geological Strength Index (GSI) Method on this mine road is the focus of this research. The Geological Strength Index (GSI) is a rock mass classification system developed to assist the inaccurate Rock Mass Rating System (RMR) in determining the quality of rock masses that have very poor conditions or have undergone very strong rock deformation. using the GSI value by using two quantitative parameters, namely the condition of the discontinuity plane and the density of the discontinuity plane. The value of the Geological Strength Index (GSI) at location points 1, 2, 3, 4 and 5 is 32,17,12,2, 33.4 and 23. The rock mass value indicates that the rock mass quality in the study area has poor rock mass quality. to very bad. The results of this investigation become a reference in the method of handling slopes on mining roads.
