PT RIMAU TANGGUH PERKASA GEOTECHNICS, HYDROLOGICAL AND HYDROGEOLOGICAL STUDIES

PT Geo Labora Expert team has become a strategic partner for various mining companies, particularly open-pit coal mines across Kalimantan. Supported by experienced specialists and reliable technical equipment, the company delivers precise geological and geotechnical analyses to support the implementation of Good Mining Practice for all clients.
Within its technical service scope, PT Geo Labora Expert team possesses core competencies that include surface geotechnical mapping, full-coring geotechnical drilling, geotechnical logging (RQD, core recovery, lithology, structural features), and slope stability analysis for both pit and disposal areas. The company also maintains strong capabilities in hydrology and hydrogeology studies, covering infiltration rate measurement, rainfall analysis, surface runoff calculation, aquifer identification, and slug testing to determine hydraulic characteristics of rock and soil. These competencies are further strengthened by
laboratory facilities that provide physical and mechanical parameters essential for slope modeling.
The services offered include open-pit geotechnical studies, hydrology and hydrogeology assessments, geotechnical drilling and sampling, rock and soil laboratory testing, two- and three-dimensional slope stability modeling, slope design and redesign recommendations, as well as geological and geotechnical map development. All services are conducted based on scientific methodology, mining industry technical standards, and comprehensive analytical approaches.
One of the flagship past projects completed by PT Geo Labora Expert teamis the 2023 open-pit geotechnical study for PT Rimau Tangguh Perkasa (PT RTP). The scope of work included surface geotechnical mapping, geotechnical drilling at four locations, infiltration testing, hydrogeological investigation, and laboratory testing to obtain geotechnical parameters of rock and soil. The technical data were then used for slope modeling under actual, design, and redesign conditions, resulting in safe, stable, and economically optimized mining slope geometries. The deliverables included a comprehensive report with slope analyses, technical maps, cross-section models, and recommendations for continued geotechnical management to support mining operations
