Abstract    The research area is located at Batu Hijau Mine PT Amman Mineral Nusa Tenggara, administratively located at the southwestern of Sumbawa, West Nusa Tenggara Province Indonesia. The research area is controlled by tectonism in accordance to close with the active tectonic plate at southern part of this island. The presence of the active tectonic regime causes of the rich deposit of ore mineralization and intensive of geological structure in this region. The study was focused on how to develop geotechnical domain which is an important aspect for developing of open pit mine design. The data collecting methods are obtaining by the window and scanline geotechnical mapping in line with excavation stage to execute pit slope design. The research result shows that the geological information is very useful to determine the geotechnical domain. It can be used for guidance on developing pit slope design parameter in open pit mining, and other geotechnical purpose such as defining probability of failure, slope movement guidance, and risk assessment.


Keywords    Batu Hijau Mine; Geotechnical Domain; Geotechnical Mapping


چکیده    منطقه تحقیق ناحیه معدن باتو هیجو از معادن جنوب غربی استان تنگارا اندونزی است. منطقه تحقیق بخش عمرانی کنترل شده طبق طرح معماری بخش جنوبی این جزیره است. حضور رژیم معماری فعال که غنی از ذخائر معدنی و ساختار زمین شناسی در این ناحیه است. تمرکز مطالعات بر چگونگی تکامل دامنه زمین شناسی که از اهمیت خاصی در تکامل و طراحی معدن رو باز برخوردار است. این تحقیق نشان داده است که اطلاعات زمین شناسی برای شناسایی دامنه ژئوتکنیکی زمین بسیار مفید می باشد. اطلاعات حاصل از این تحقیق راهنمای مناسبی برای طراحی شیب و پارامترهای موثر معدن روباز است که از ویژگی آن شناسائی خصوصیات ژئوتکنیکی معدن همانند تعیین و بررسی هرگونه خطر و ریسک سقوط و خطا احتمالی ریزش معدن را بررسی نماید.
