Abstract

PT. Bumi Karya Makmur is one of the companies engaged in coal mining contractors. PT. Bumi Karya Makmur is a mining contractor trusted by PT. International Prima Coal as the holder of IUP OP (Production Operation Mining Business License) to carry out coal mining activities which located in Bantuas, Palaran District, Samarinda City, East Kalimantan Province. Mining activity is carried out using the Open Pit Mining method. In May 2021, a landslide occurred on the western slopes of Pit Eagle 1 which have made  disrupted mining activities because the front work was buried by slope of landslide material. The landslide was caused by the actual geometry of the slopes in the field which is too steep around 80° for single slope and there were puddles of water on the slopes that makes the slope in the saturated state. The slope stability analysis of the western area at Pit Eagle 1 used the Probabilistic Monte Carlo method, where the initial soil data were: cohesion (c) = 93,272 kN/m2 and internal shear angle (ϕ) = 20,122˚; sandstone: (c) = 87,886 kN/m2 and (ϕ) = 28,014; mudstone: c = 129.983 kN/m2 and = 31,317˚. Analysis the value of the factor of safety (FK), the probability of landslides (PK), and slope geometry recommendation using the Bishop Simplified method. The results of this research are, firstly, the slope safety factor value at Pit Eagle 1 in the saturated state before the landslide is 1.253 with a landslide probability value of 0%, in the semi-saturated state with FK value is 1.602 with a landslide probability value of 0% and the dry state with a FK value of 1.802 with a probability of avalanche 0%. Secondly, back analysis on the Pit Eagle 1 landslide area resulted in the value of the geotechnical parameter Soil (C) = 88.6 kN/m2 (ϕ) = 20,122o; Sandstone: (c) = 87,886 kN/m2 and (ϕ) = 28,014o; Mudstone (C) = 69.65 kN/m2 (ϕ) = 23.316o. Third, the geometry recommendation of slope at Pit Eagle 1 with an overall slope height of 40 meters, that namely with an overall slope angle of 52˚ with a single slope height of 8 meters, a bench width of 5 meters, and a single slope angle for Soil and Sandstone materials, while for a single slope angle for Mudstone materials is 70°.

Abstract

Abstract. PT. Kalimantan Prima Persada is a coal mining company, one of its working locations is PT. PCN (Prolindo Cipta Nusantara) The mining pit is named the Majapahit Pit. At the Majapahit Pit, a new road was built that functions for the overburden transportation road, namely Jalan Arjunasastra and Jalan Putri Gunung Buih.Many road segments have non-ideal road geometry, based on speed data of Komatsu HD 785-7 loaded and unloaded equipment it was found that 35.48 km/hour and 12.01 km/hour. This is not in accordance with the company's target, where the target speed of the HD 785-7 conveyance is 17 km/hour and 50 km/h empty. As a result of not achieving the speed, it will affect the production of transportation equipment in March-April, based on data on the production of Komatsu HD 785-7 transportation equipment, which is actually 231.860 Bcm but the company's target is 288.000 Bcm. As a result of not achieving production, it affects the value of the fuel ratio of the conveyance. Based on fuel ratio data, the actual conveyance is 0.68 Bcm/hour but the company's target is 0.54 Bcm/hour.The effect of total resistance on speed is inversely proportional, meaning that if the total resistance increases, the speed decreases. And the effect of total resistance on the fuel ratio is directly proportional, meaning that if the total resistance increases, the fuel ratio increases. This is in accordance with the results of the improvement. After repairs were made, it was found that the speed value for the loaded condition increased to 17.91 Km/hour and the empty condition became 50.05 Km/hour so that it increased by about 40%, for the production of transportation equipment it increased to 294,307 Bcm/hour so that it rose 23,52% and fuel ratio decreased to 0.54 Bcm/hour so that the fuel ratio decreased by 25,93%.

Abstract

PT. Sumbar Calcium Pratama is a company engaged in open pit mining and processing of l imestone in Jorong Ateh Loban, Nagari Halaban, Lareh Sago Halaban District, Fifty City District, West Sumatra Province. In supporting its production, PT. West Sumatra Calcium Pratama requires an effective road access design that complies with standards so as not to hinder production activities. From the actual data in the field, it was found that the road segments had non-ideal straight road widths, namely segments 1, 2, 3, 4, 5, and 9, while the ideal straight road width after calculations was 7 meters, on the bend road width t here were four non-ideal road segments, where the ideal road bend width is 10.5 meters. Then there is a road grade that is > 10% to be precise in segment 8 (12.25%) which of course this is not in accordance with t he applicable provisions according to AASHTO 1994. Because this will certainly affect the total rimpull, speed, circulation time, and productivity of the tool transport. From the calculation results, the actual productivity value of the conveyance is 1.47 tons/hour, while the planned productivity of the conveyance with a hauling distance of about 2.8 km is 2.08 tons/hour. After the theoretical calculations were carried out with the road conditions having been repaired, the productivity of the transportation equipment was 2.18 t ons/hour, which means that after the road was repaired theoretically the productivity reached even more t han the plan. While the production target in February was 2,000 tons/month, with actual production of 1,416 tons/month. After doing theoretical calculations, it was found that production was 2,100 tons/month, which means that it exceeded the production target. The conclusion of this study is that road conditions will affect the total rimpull, the total rimpull will affect the speed, then the speed will affect the cycle time, and t his cycle time will affect the productivity of the conveyance.

Abstract

 Abstract.  Haul roads are a facility of crucial importance in mining activities, connecting various location points throughout mining, processing, and sales operations.  Optimal and efficient planning is necessary to meet the need for haul roads. Road planning is undertaken to acquire the road geometry required. This includes the bearing capacity of the soil, which is crucial in determining the weight of vehicles that the road can sustain. Therefore, the essential data that is required for the planning process includes the conveyance specifications and the findings from the Dynamic Cone Penetrometer (DCP) test. Based on the executed plan, it was determined that the minimum width required for the haul road is 8.75 m, and 15.14 m at the bend. In addition, the plan's superelevation value is 0.04 (equivalent to 4%), a cross slope of 18 cm, a safety berm of 0.5 m, a bottom width of 1.5 m, and the minimum stopping distance is 19.61 m. Technical term abbreviations are explained upon first use. For the design of pavement thickness on the base layer that has been calculated using the DCP test, it is noted that CBR values not compliant with established standards necessitate backfilling if the result is ≤ 5% and compaction if the result is ≥ 12%, ensuring the planned road meets required standards.
