Abstract

PT. Cahaya Ganda Gindi is a nickel company engaged in lateritic nickel mining. The company's nickel ore mining activities have now entered the operational phase, including topsoil stripping, overburden removal, lateritic nickel mining, and lateritic nickel transportation. The mining area, which is located close to residential settlements, has some impact on community activities. Therefore, these impacts need to be managed to prevent disturbances to the daily activities of local residents. The production activities, which involve overburden stripping and lateritic nickel ore extraction using heavy machinery, inevitably generate high levels of noise that may affect the hearing of nearby residents. Noise level testing is conducted in the mining area, jetty, and residential areas by measuring noise levels at specific points. The collected data is then analyzed to determine whether the noise levels remain within the permissible limits. The goal is to ensure that the noise does not exceed the established threshold, allowing the community to carry out their activities normally.

Abstract

Monitoring and evaluation of blast fragmentation are critical to achieving the most optimal design and outcomes. Several methods are utilized to assess the effectiveness of blasting in the field, one of which is the digital image analysis method, which has gained popularity in recent years. This study aims to apply the digital image analysis technique to rock fragments resulting from blasting and compare the results with empirical analysis using the Kuz-Ram equation. The digital image analysis was conducted using data from three blasting activities in a limestone quarry, with the number of blast holes as follows: 130 in blast-01, 86 in blast-02, and 90 in blast-03. The spacing and burden used in the blast designs were 2.5 m and 2 m, respectively, for all three blasting activities. The results revealed that the largest deviation of 60% occurred at the 10 mm sieve size for blast-02 compared to the Kuz-Ram model. Rock fragments from blast-01 passed 80% at a sieve size of ±280 mm, while for blast-02 and blast-03, 80% of the material passed at sizes >=600 mm. The analysis showed that the percentage passing graph R(X) for all three blasting activities, as determined through the Kuz-Ram method, exhibited relatively close values, albeit with some deviations. After analyzing the three blasting activities with identical designs, the results obtained using the WipFrag software demonstrated satisfactory performance for preliminary field monitoring purposes.

Abstract

The process of mining nickel resources at PT Gahnesa Wana Utama has problems in the form of differences in nickel content between the drill data and mining results data. Therefore, this study aims to determine the proportion of nickel grade values from drilling to mining results and to determine the factors that cause changes in nickel content values from drilling and mining results. The research method is carried out by analyzing the results of drill data with mining results. The results of the study showed that the drilling results obtained an average grade value of 1.64%, while mining results obtained an average grade value of 1.42%. This study shows that there has been a comparison of the difference in Ni content based on the results of drilling and mining results, namely 0.22%. The causative factors of changes in nickel levels are stagnant water in the stockpile, use of used sacks for samples, dredging of stockpile floors that are less clean, operators who are less attractive in ore collection, sampling errors and preparation errors.
