Abstract

Open access land mining activities on the Lubuk Selasih – Surian national road have in floods and landslides that have, in losses to the community and the imposition of costs for maintenance and rehabilitation of federal roads along the mining area. This study aims to determine the existing condition of mining and analyze the vulnerability of erosions in mining areas. The data used is secondary data, using descriptive quantitative methods with photogrammetric analysis of the maps obtained. The results showed that this mining area has the characteristics of rocks that are easily crushed and tend to be unstable, as well as steep and very steep slopes. This area is also located on the active Semangko fault and volcanic mountains. The environmental carrying capacity of disaster prevention and protection ecosystem services is mainly in the shallow categories. Based on these findings, the mine site is at a very high level of vulnerability to erosions. Thus, it is necessary to mitigate mining management administratively and operationally to minimize environmental damage
