Analisis perbandingan volume kemajuan tambang terhadap mine plan design pada aktivitas penambangan di pit central west 8 pt roda jaya sakti, kabupaten morowali, sulawesi tengah.
P Perbandingan volume kemajuan tambang berdasarkan desain penambangan digunakan sebagai acuan dalam evaluasi terhadap kinerja dari berbagai pihak terkait, karena hasil antara volume overburden yang telah dikupas dengan volume survey menggunakan sistem komputerisasi data progress (software Surpac 6.6.2) selalu berbeda. Oleh karena itu, dengan adanya penelitian ini diharapkan dapat membantu untuk mengevaluasi pengambilan material berharga dan pengupasan lapisan tanah penutup. Penelitian ini dilakukan di pit Central West 8 PT Roda Jaya Sakti, Desa Tangofa, Kecamatan Bungku Pesisir, Kabupaten Morowali, Propinsi Sulawesi Tengah. Pada tahun 2023 PT Roda Jaya Sakti mempunyai kontrak penambangan dimana pengambilan volume material pada desain penambangan dilakukan pembayaran single rate (dibayarkan hanya pada material ore getting saja), sehingga volume overcut, undercut dan in of plan pada desain penambangan sangat menjadi perhatian khusus. Total volume ore getting pada periode Desember 2023 yaitu berdasarkan data truck count sebesar 216.784 BCM dan berdasarkan data survei sebesar 216.786 BCM. Dan total volume overburden pada periode Desember 2023 yaitu berdasarkan data truck count sebesar 152.372 BCM dan berdasarkan data survei sebesar 164.213 BCM. Selisih dari data truck count dengan data survey progress sebesar 11.841 BCM dengan persentase deviasi keseluruhan sebesar 2,21 % yang artinya nilai volume truck count lebih kecil dari pada volume survei. Progres kemajuan tambang di RL 424 – 361 Mdpl dengan kedalaman penggalian 7 – 17 meter. Studi ini menyarankan perlunya perbaikan dalam prosedur pengumpulan dan pengolahan data, serta pemanfaatan teknologi yang lebih canggih untuk meningkatkan akurasi perhitungan volume. Hasil penelitian ini diharapkan dapat memberikan kontribusi dalam meningkatkan efisiensi dan efektivitas operasi penambangan di PT Roda Jaya Sakti.
C Comparison of mine progress volume based on mining design is used as a reference in evaluating the performance of various related parties, because the results between the overburden volume that has been stripped and the survey volume using a computerized progress data system (Surpac 6.6.2 software) are always different. Therefore, it is hoped that this research can help evaluate the extraction of valuable materials and stripping of the overburden. This research was conducted at the Central West 8 pit of PT Roda Jaya Sakti, Tangofa Village, Bungku Pesisir District, Morowali Regency, Central Sulawesi Province. In 2023 PT Roda Jaya Sakti has a mining contract where the volume of material taken in the mining design is paid in a single rate (paid only for ore getting material), so that the volume of overcut, undercut and in of plan in the mining design is of particular concern. The total volume of ore getting in the December 2023 period, based on truck count data, is 216,784 BCM and based on survey data is 216,786 BCM. And the total overburden volume in the December 2023 period, based on truck count data, is 152,372 BCM and based on survey data is 164,213 BCM. The difference between the truck count data and the survey progress data is 11,841 BCM with an overall deviation percentage of 2.21%, which means the truck count volume value is smaller than the survey volume. Mining progress at RL 424 – 361 masl with excavation depth of 7 – 17 meters. This study suggests the need for improvements in data collection and processing procedures, as well as the use of more sophisticated technology to increase the accuracy of volume calculations. It is hoped that the results of this research can contribute to increasing the efficiency and effectiveness of mining operations at PT Roda Jaya Sakti.
