Analisis Tingkat Kebisingan Pada Area Mesin Pertambangan Bawa Tanah

Abstract

Underground mining poses significant risks, and one such hazard is noise. High-speed machines operating in underground mines generate noise. This study particularly targets areas like stockpile 04, stockpile 05, stockpile 06, and the portal due to the concentration of machinery in these zones.The detrimental impacts of noise on human health are well-documented, including increased blood pressure, which can contribute to various health issues, as well as psychological and communication disorders. To mitigate these risks, it is essential to conduct thorough noise analysis to determine suitable noise reduction measures. One method employed for analysis involves calculating noise levels using a sound level meter. Additionally, mapping and analysis of emergency alarms require coordinate values. Noise level calculations utilize the Leq formula, with a time variation of 10 minutes for mapping and 2, 6, and 14 minutes for analyzing different time variations.The findings reveal that stockpile 04 registers the highest noise level at 113.9 dBA, whereas the portal location records the lowest at 67.1 dBA. Furthermore, emergency alarms contribute an additional 6 dBA to the overall noise level at the research site. Analyses incorporating time variations of 2, 6, and 14 minutes demonstrate noise levels remaining below 2%
