Abstract

PT. Satria Alam Manunggal is a company specializing in mining, specifically as a mining contractor for PT. Telen Orbit Prima (TOP). One of its activities is the removal of overburden. The purpose of this study is to analyze the match factor of loading and hauling equipment in the removal of overburden. Using quantitative and descriptive methods, the researchers examined issues related to the match factor in overburden stripping activities at the PT. Satria Alam Manunggal TOPB site. From the observations, the cycle time of the loading equipment in fleet 1 was 26.40 seconds or 0.44 minutes, while in fleet 2 it was 27.75 seconds or 0.46 minutes. The cycle time of the transport equipment in fleet 1 was 833.1 seconds or 13.89 minutes, while in fleet 2 it was 930 seconds or 15. 50 minutes. From the cycle time of the loading and transport equipment in both fleets, the compatibility value in fleet 1 was 1.14 and in fleet 2 was 1.07. The factors that hindered the compatibility of the loading and transport equipment were the excavator waiting for the dump truck to maneuver, the difference in speed between dump trucks, and the loading time being too long

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh parameter geometri peledakan terhadap nilai Scaled Depth of Burial (SDoB), Powder Factor (PF), fragmentasi, dan waktu gali (digging time) pada kegiatan peledakan tanah penutup di Pit Warute,PT. Bina Sarana Sukses (BSS) Jobsite Antang Gunung Meratus, Kalimantan Selatan. Data diperoleh dari lima belas kegiatan peledakan dengan variasi burden, spasi, kedalaman lubang, dan panjang stemming. Hasil penelitian menunjukkan bahwa nilai SDoB berkisar antara 1,00–1,38 m·kg⁻¹ᐟ³ dengan rata-rata 1,19 m·kg⁻¹ᐟ³, sedangkan PF berada pada kisaran0,11–0,17 kg·m⁻³ dengan rata-rata 0,14 kg·m⁻³. Analisis regresi linier memperlihatkan bahwa hubungan antara SDoB terhadap fragmentasi dan digging time bersifat lemah, dengan nilai koefisien determinasi masing-masing sebesar R² = 0,042 dan R² = 0,015. Demikian pula, PF tidak menunjukkan pengaruh signifikan terhadap kedua parameter tersebut.Meskipun demikian, secara empiris ditemukan bahwa kombinasi geometri peledakan dengan burden 7 m, spasi 9 m, kedalaman lubang 7–8 m, dan stemming 3 m memberikan hasil fragmentasi yang lebih seragam serta waktu gali yang lebih efisien. Dengan demikian, rentang nilai SDoB antara 1,10–1,25 m·kg⁻¹ᐟ³ direkomendasikan sebagai kondisi optimumuntuk kegiatan peledakan di Pit Warute.
