Abstract

Blasting is an activity that breaks rocks from their parent rock using explosives to create smaller fragments, making the loading and transportation processes easier. One of the environmental impacts of blasting activities is ground vibration. Ground vibration is one of the outcomes of blasting activities, and it is measured using the PPV (Peak Particle Velocity) value. Ground vibration can become a problem for companies if it exceeds the safe vibration quality standard (SNI 7571: 2010), as it can pose a danger to humans and nearby buildings. The Air Deck is an air column in the blast hole that aims to reduce energy vertically, this method can reduce the use of explosives. This research was conducted at the Sentuk Pit of PT. Multi Harapan Utama in East Kalimantan. Observations were made during 42 blast events to determine the impact of the air deck method on the resulting vibration. During the study, the maximum PPV value was 13.87 mm/s, while the minimum PPV value was 1.13 mm/s. The average ground vibration measurement value for non-air deck blasting was 4.40 mm/s, while the average ground vibration measurement value for air deck blasting was 3.95 mm/s. The use of this method also reduced the powder factor value. For non-air deck blasting, the average powder factor value was 0.26 kg/m³, and for air deck blasting, the powder factor value was 0.20 kg/m³, resulting in a 23.08% reduction in explosive usage. To calculate the predicted PPV, scaled distance calculations were used. Based on the predicted PPV calculation results, the deviation from the actual PPV was 1.59 mm/s.

Abstract

This research aims to compare coal quality based on proximate analysis in two seams with varying depths in Pit North and evaluate the relationship between depth and coal quality parameters. The research method includes taking representative samples at each seam and proximate analysis laboratory testing including inherent moisture, ash content, volatile matter, and fixed carbon. The results showed that seam 1 at an average depth of 59.8 m had an inherent moisture value of 13.51%, ash 4.68%, volatile matter 39.93%, and fixed carbon 41.88%, while seam 2 at an average depth of 82.1 m had inherent moisture 13.42%, ash 4.59%, volatile matter 40.15%, and fixed carbon. 41.84%. Correlation analysis shows that the relationship between depth and coal quality parameters is relatively weak with correlation coefficient values ​​ranging from −0.36 to 0.25 and a low coefficient of determination, so that variations in depth do not have a significant influence on coal quality at the research location.

Abstract

At the research location at PT. Ansaf Inti Resource, there are several mining stages such as exploration. In the exploration itself, drilling and logging activities are carried out. However, if not careful in calculating coal resource estimates, there can be potential discrepancies between the estimated coal resources based on the results of drilling data identification and well logging data with the actual results. Exploration activities are activities that are often carried out by companies to determine reserves in an area. Without carrying out these activities, companies will have difficulty estimating the profits to be obtained. To obtain the data needed to carry out exploration activities such as calculating the quality and quantity of coal, it is necessary to carry out drilling such as the full coring method and also carry out logging activities to complete the data and also as comparative data from core drilling. Coal Resources are part of a coal deposit in the form of a certain quantity and have reasonable prospects that allow for economic consideration. Coal resources are divided according to the level of geological confidence into inferred, indicated, and measured categories. Therefore, in this study, the author will calculate coal resources from exploration data collection such as coring data, cutting data, and well logging data as well as coal quality data and process it in Minescape 5.7 software so that it can obtain an estimate of coal resources for each seam at the research location.

Abstract

Bukit Baiduri Energi is a coal mining company operating in Bukit Raya Village, Tenggarong Seberang District, Kutai Kartanegara Regency, East Kalimantan Province. The coal produced has different sizes so it cannot be sold directly. Therefore, it is necessary to carry out a grain size reduction process (crushing) to meet market needs (buyers). The production target of the crushing unit is 128,000 tons/month, based on actual observations in the field, it only produces 110,065.27 tons/month, which means the crusher plant unit only produces 86%, still lacking 14%. Productivity at CP-01 is 317.73 tons/hour and CP-02 is 214.47 tons/hour. The production target has not been achieved due to several constraints (technical and non-technical), it is necessary to conduct a constraint time analysis using a Pareto diagram to determine the efforts that must be made to achieve the production target. For the work efficiency value at CP-01 it is only 27.04% and for CP-02 it is only 31.21 and for the value of the availability of working time of the crusher plant unit, the value at CP-01 is MA = 81.94%, PA = 28.75%, UA = 90.04%, EU = 27.04% and at CP-02 it is MA = 83.31%, PA = 32%, UA = 94% and EU = 30%. The production of the crusher unit after improving the working time constraints is able to produce 328,021.15 tons/month.
