Abstract

Rock mass is a volume of rock consisting of rock material in the form of minerals, texture, composition and also consisting of discontinuous planes, forming a material and interconnected with all elements as a unit. The rock mass itself is composed of several intact rocks which basically have isotropic, continuous and homogeneous properties. However, the conditions found in the field are different, namely anisotropic, discontinuous and heterogeneous. These properties will certainly influence the test results in the uniaxial test. There are several factors that influence the results of uniaxial rock tests, one of which is the scale effect. The purpose of this test is to determine and analyze the effect of rock sample size on the uniaxial compressive strength value of claystone. This rock testing was carried out at the Mineral and Coal Technology Laboratory and the rock sampling locations were in Palaran District, Samarinda City and in North Samarinda District, Samarinda City. In this uniaxial compressive strength test, 3 side widths with different lengths will be used. After carrying out the uniaxial compressive strength test, the average uniaxial compressive strength test value was obtained in each formation, such as the Balang Island formation, the average rock compressive strength test value was 1.68 Mpa and the Balang formation, the average rock compressive strength test value was 3.10. Mpa. Based on these results, it can be concluded that the larger the sample size, the smaller the rock compressive strength test value tends to be.

Abstract

Uniaxial Compressive Strength is a test method to classify the strength and characterization of intact rock. Where it is important information in determining the strength and characteristics of a rock obtained by testing using the UCS tool. In this research, an alternative is made in determining the UCS value precisely and easily, namely by using the schmidt hammer test and compressive strength test. Therefore, this research aims to obtain the correlation value between the results of the compressive strength test and the schmidt hammer test on siltstone.This research is a quantitative research, so that to obtain accurate calculation data, testing methods are used in the form of compressive strength tests on rocks and schmidt hammer tests, which in this case are tested on siltstone samples. In this study, 2 rock formations were used, including the Pulau Balang formation and the Kampung Baru formation, so that the accuracy of the test results can be obtained properly. Based on the results of observations and calculations that have been made, it can be concluded that the correlation of the uniaxial compressive strength value with the rebound number schmidt hammer value shows a positive linear correlation between the UCS value and the rebound number schmidt hammer value, in this case it can be seen when the uniaxial compressive strength value is higher, the rebound number schmidt hammer value is also higher.

Abstract

Rotary drilling is one of the drilling methods that is often used for stripping overburden in open pit mining activities. In the rotary drilling process, prediction of the penetration rate is very important for scheduling production and estimating drilling costs. Drilling in mining activities is used, among other things, to create blast holes. In blasting activities, drilling is the first activity that must be carried out to provide a blast hole which will later be filled with explosives to be detonated. Meanwhile, the speed at which the blast hole is prepared is influenced by the speed of the drilling tool to penetrate the rock. Drilling speed is influenced by two factors, namely internal factors and external factors.

Abstract

Drilling is an essential operation in mining activities, particularly in borehole preparation for blasting purposes. The efficiency of blasting hole preparation depends significantly on the drilling speed to penetrate the rock formations.Drilling Rate Index (DRI) measures the ease or difficulty of drilling through rock formations. It combines two tests: Brittleness (S20) and SJ value. DRI serves as a common metric to predict drilling capabilities and is classified according to a table classification of drilling rate index.The classification of DRI values for sandstone and mudstone of Balikpapan Formation at PT. RCI Job Site ABK indicates a very high classification with DRI values ranging from 66 to 86. Testing results for samples SBP1 (DRI 75.9), SBP2 (DRI 81.7), SBL1 (DRI 66.6), and SBL2 (DRI 71.1) all fall within the very high classification range.

Uniaxial Compressive Strength is a test method to classify the strength and characterization of intact rock. Where it is important information in determining the strength and characteristics of a rock obtained by testing using the UCS tool. In this research, an alternative is made in determining the UCS value precisely and easily, namely by using the schmidt hammer test and compressive strength test. Therefore, this research aims to obtain the correlation value between the results of the compressive strength test and the schmidt hammer test on sandstone. Based on the results of observations and calculations that have been carried out, it can be concluded that the compressive strength value in the Balikpapan formation is lower than the compressive strength value in the Pulaubalang formation where the compressive strength value in the Balikpapan formation is 3.3 MPa-4.3 MPa, while the compressive strength value in the Pulaubalang formation is 4.3-5.57 MPa. The rebound number in the Balikpapan formation is lower than the rebound number in the Pulaubalang formation, where the rebound number in the Balikpapan formation is 16-17.8, while the rebound number in the Pulaubalang formation is 18-22.3. The correlation of the uniaxial compressive strength value with the rebound number of the schmidt hammer shows a positive linear correlation between the UCS value and the rebound number of the schmidt hammer, in this case it can be seen that when the uniaxial compressive strength value is higher, the rebound number of the schmidt hammer is also higher.

Abstract

Mining roads are one of the most important facilities that greatly affect the smoothness of production and affect mining costs. Therefore, the construction of mining roads must be carried out carefully to meet technical and work safety standards. Road conditions, distance, road slope and road carrying capacity will greatly affect the production capacity of heavy equipment, especially the production capacity of transport equipment. The location of this research is at PT. Energi Cahaya Industritama, precisely in Palaran sub-district, Samarinda city, East Kalimantan province. After observations were made at the research location, it was found that the geometric conditions of the road did not comply with the standards based on the overburden transport equipment or the largest transport equipment, for example, the width of the road on bends and the slope of the road. After conducting the research, the results of the data from the geometry of the access road were obtained, namely, the actual condition of the geometry of the access road on the straight road width is divided into 6 segments with a width of 13.3 meters, 14.3 meters, 14.5 meters, 13.2 meters, 15 meters, 15.7 meters. Meanwhile, the width of the bend road is also divided into 2 segments with a width of 15.9 meters and 15.5 meters respectively. And on the slope of the road there are 2 segments with values ​​of 11.1% and 14.8% respectively. Based on the results of the simulation software, the productivity of the transport equipment was obtained at 92.42 BCM/hour, which shows that productivity has increased by 12.23 BCM/hour from the actual productivity value of 80.109 BCM/hour. It has an average cycle time of 10.33 minutes, which shows a reduction in time or 6.01 minutes faster than the actual average cycle time of 16.34 minutes.

Abstract

Dump truck tires are an important component in the operation of wheel-type units that require routine inspection because they directly affect the availability and performance of the transport equipment. In the OHT 777 type unit, six tires are used with a configuration of two tires in the front and four tires in the rear. This study aims to evaluate tire performance through the analysis of Key Performance Indicator (KPI) parameters, namely Ton Kilometer Per Hour (TKPH), Tread Utilization Rate (TUR), and tire life (lifetime), in order to assess the achievement of performance targets. The research method uses a quantitative approach with actual data collection in the field, including the preparation stages, primary and secondary data collection, data processing, and preparation of the final report. The data is processed to obtain the tire KPI value. The results of the analysis show that the TUR value for MICHELIN brand tires is 68.9% and BRIDGESTONE is 70.7%, still below the company's target of 85%. The TKPH value for the OHT 773 unit is 149 (with a TKPH rating of 207) and the 777 unit is 241 (with a TKPH rating of 514). The actual lifetime of BRIDGESTONE tires was recorded at 1,698.6 hm and MICHELIN at 2,268 hm, far below the target of 8,500 hm. Tire damage found included impact (23%), sidewall damage (18%), run flat (18%), bread damage (18%), sounder cut (14%), and foreign object puncture (9%). This evaluation is expected to be the basis for improving tire management, so that tire performance in the future can be more optimal and support the smooth operation of the unit.

Abstract

Landslides or commonly called landslides are a disaster that often hits areas with tropical climates. The damage caused by landslides is most dominantly structural damage such as damaged road sections that are cut off. At the research location, there was a landslide that resulted in the obstruction of the road flow which was originally two lanes to one lane, it is feared that landslides will occur again, so one of the landslide prevention techniques is to use retaining walls. Based on this, this study is deemed necessary to determine the slope safety factor and to determine the safety of the slope after using retaining walls. The purpose of this study was to determine the level of slope safety without being given a load, the level of slope safety after being given a load of 25 Kpa and the level of slope safety after being given a load of 25 kpa and the addition of a retaining wall on the research slope using a Retaining Wall. In this study using the Finite Element Method in the calculation to find the level of safety of a slope, the researcher used the help of Plaxis 2D V20 Software, and the results of the calculation obtained a slope safety factor of 1.31, after being given a load of 25 kpa the slope safety factor was 1.14 and after being given a retaining wall the slope safety factor increased to 2.46.
