Abstract

Metode kerja penggalian yang dilakukan saat ini di PT. MME adalah free digging dan ripping. Kajian teknis yang dilakukan untuk menentukan apakah material overburden yang digali apakah memang benar-benar free digging atau ripping, sesuai dengan karakteristik massa batuan dan kemampuan digging force alat gali-muat belum dilakukan penelitiannya. Pengaruh dari digging force dan karakteristik mekanis batuan terhadap unit adalah pada productivity yang menurun jika metode penggalian yang dilakukan tidak tepat dan juga terkait kinerja unit yaitu PA, MA, UA, dan EU. Setelah dilakukan penelitian, maka didapatkan jika material yang digali oleh alat gali muat EX1250 dan EX900 berupa material siltstone dengan nilai kuat tekan (UCS) sebesar 0,67 MPa. Sedangkan berdasarkan spesifikasi, nilai digging force masing-masing alat yaitu 0,60 Mpa untuk EX1250 dan 0,48 Mpa untuk EX900, berada di bawah nilai UCS material siltstone. Hal ini mengakibatkan adanya deviasi pada nilai productivity alat gali-muat. Pada unit EX1250, productivity dengan metode direct digging (512,52 Bcm/jam) lebih kecil dibandingkan dengan metode penggalian material ripping (552,67 Bcm/jam), yaitu sebesar 40,15 Bcm/jam. Sedangkan untuk unit EX900, productivity dengan metode direct digging sebesar 42,77 Bcm/jam, sedangkan productivity dengan metode penggalian material ripping sebesar 471,77 Bcm/jam, terdapat deviasi 50,99 Bcm/jam. Selain itu, metode penggalian direct digging dengan menggunakan unit EX1250 dan EX900 pada material siltstone, berpotensi untuk menurunkan kinerja mekanis dan utilisasi pada alat gali-muat.

Abstract

This research was conducted with a back analysis on the pit 1 slopes of PT Bukit Asam, TBK where material deformation occurred due to saturation from material above the slope that previously contained a settling pond holding water from other pits. Slope stability analysis is necessary to achieve a stable slope geometry with FoS >1.25. The analysis performed for determining this FoS involves back analysis to obtain stable slope geometry and to calculate changes in coal recovery due to geometric changes in the excavation slope. This study aims to analyze slope stability to obtain actual geotechnical parameters in the excavation slopes affected by water and their safety factors, as well as to analyze changes in mining recovery due to changes in slope geometry. Slope stability determination is carried out by conducting analysis. This research aims to analyze slope stability to obtain actual geotechnical parameters in excavated slopes influenced by water and their safety factors, as well as to conduct an analysis to determine changes in mining recovery due to changes in slope geometry. The determination of slope stability is carried out by performing a back analysis on the excavated slopes that have experienced deformation, resulting in new geotechnical parameters that have been degraded. The degradation of geotechnical parameters on the slope of Pit 1 excavation resulted in a decrease in cohesion (C) by 63% from 77.14 Kpa to 28.26 Kpa, and the internal friction angle (Ǿ) decreased by 32% from 27.16° to 18.35°. The degradation of geotechnical parameters on the slope of Pit 1 caused a mining recovery decrease of 61.7%, where the initial pit slope plan of Pit 1 was expected to yield 4,750,000 tons of coal, while the revised pit slope plan of Pit 1 yielded 2,820,000 tons of coal.

Abstract

This study examines the influence of the implementation of the Mining Safety Management System (SMKP) on workplace accident rates within coal mining operations. A quantitative research design was adopted, utilizing survey data obtained from 390 employees working in mining companies operating under IUP PMDN in South Sumatra. The variables investigated consist of technical risk control, adherence to Standard Operating Procedures (SOP), safety training and emergency drills, and the utilization of Personal Protective Equipment (PPE). Data analysis was conducted using multiple linear regression to assess both the individual (partial) and combined (simultaneous) effects of the independent variables on accident rates. The findings indicate that the regression model is statistically significant, with a coefficient of determination (R²) of 0.436, suggesting that 43.6% of the variability in workplace accidents is explained by the variables included in the model. At the individual level, safety training and PPE utilization demonstrate a significant effect on accident rates, whereas technical risk control and SOP compliance do not exhibit a statistically significant influence. These results suggest that behavioral aspects have a more prominent role compared to system-related factors in mitigating workplace accidents. Accordingly, this study underscores the need to prioritize the enhancement of safety training programs, strengthen safety awareness, and ensure consistent PPE compliance as critical strategies for improving safety performance in the mining industry.
