Abstract

PT JResource Bolaang Mongondow merupakan perusahaan tambang terbuka emas yang mengalami kelongsoran pada salah satu lereng di Pit Mine Ridge, Bakan Gold Project. Kelongsoran terjadi pada domain argillic dimana kelongsoran terjadi pada salah satu bench dari lereng keseluruhan. Tujuan dari studi ini yaitu menginvestigasi dan analisis geoteknik lereng di Pit Mine Ridge PT Jresources Bolaang Mongondow serta pemodelan kestabilan lerengnya. Dalam memenuhi tujuan tersebut. Hasil pemodelan kestabilan pada Lereng aktual memiliki tinggi 20,070 meter dan kemiringan 47° didapatkan FK sebesar 0,942. Menurut Kepmen ESDM No.1827 K/30/MEM/2018 bahwa lereng tersebut tergolong tidak aman, dimana FK minimum untuk analisis pseudo-statis lereng keseluruhan adalah 1 (FK>1). Geometri lereng tersebut perlu dilakukan redesign untuk mendapatkan geometri yang lebih aman. Simulasi dilakukan dengan mencoba tinggi dan kemiringan yang sesuai hingga didapatkan FK stabil. Didapatkan FK 1,035 pada lereng dengan geometri kemiringan yang diturunkan menjadi 33° (single bench). Lereng tersebut masih dapat dibentuk menjadi double bench dan triple bench dengan FK masing-masing 1,055 dan 1,042. Setelah melakukan re-design terhadap lereng, penting untuk melakukan pemantauan terhadap muka air tanah dan juga deformasi pada lereng.

Abstract

Andesite and basalt are generally mined materials used only for building (construction). To increase the added value, basalt rock is currently starting to be widely used as a construction material that is converted into composites with fiber reinforcement. In this initial research, the aim is to examine the characteristics of basalt rock at three locations in the Greater Bandung area (Gunung Bohong, Cipatik, and Batu Templek), including its chemical composition, physical and mechanical properties, and mineral composition. The research methodology is carried out on three rock characteristics that can be used as basalt fiber, namely the XRF method to determine chemical composition (Al2O3 and SiO2), physical and mechanical testing, as well as the petrographic analysis method to discover mineral composition by examining the presence of Plagioclase minerals. The results of the chemical analysis of all samples are suitable, but there are chemical compounds that do not match the parameters, namely Fe2O3 + FeO and MgO. Samples from Cipatik and Batu Templek are suitable. The physical properties test is also suitable. For mechanical property testing, only samples from Gunung Bohong and Cipatik are suitable. Petrographic tests conclude that the three rock samples fit into the basaltic andesite rock category.
