The comparison of physical and mechanical properties of sand in Sedau and Obel-Obel Village

Abstract The research was conducted in two regencies: Sedau Village West Lombok Regency and Obel- Obel East Regency. sites are areas with potential sand wealth, many mining companies operating. company at the site is expected to implement good practices which pay attention design safety. Geotechnical recommendations on slope dimensions a safety factor value required making design. Several factors affect rock’s geotechnical properties. These physical mechanical. In this study, comparison made between mechanical properties of locations, aims compare rock characteristics become reference for area. method used sampling testing laboratory. results showed that porosity 0.102 Obel-obel Village’s 0.09. average water content 6.567%, Obel-Obel 8.233%. specific gravity 3.75 gr/cm3, gr/cm3. compressive strength 0.137 Mpa, 2.32 MPa. Based laboratory results, influencing were analyzed, namely location its formation different processes sedimentation Village.
