Risk analysis of mining construction activities on hydrogeological vulnerability in Dompu District, East Sumbawa, West Nusa Tenggara

Indonesia is rich in natural resources due to its location at the meeting point of the Indo-Australian, Pacific, and Eurasian plates. Areas like East Sumbawa are prone to soil shifts from volcanic activity and mining. The fragile soil and mining increase the risk of soil structure changes and groundwater disruption. This research aims to examine the effects and risks of mining construction in fragile limestone regions on soil structure alterations and shifts in groundwater basin or aquifer positions. The map overlay method will visually detect landscape changes from mining, while the HVSR method will analyze subsurface phenomena like landslides. Archie’s theory will aid groundwater basin layer analysis. Archie’s theory and geoelectrical methods can identify groundwater basins for early detection and final verification of research. Blasting modeling software simulates ground vibration effects and their impact on soil structure and groundwater basins. Changes in soil structure and associated risks can be detected early. Overlaying existing maps with simulation software results provides early hazard detection information. This can be utilized to design community development activities, avoiding potential risks from construction and mining activities on fragile limestone lands.
