噪声污染是采矿活动的无意结果,需要严格的评估,监测,和缓解技术,以减少其对当地居民和生态系统的影响。该研究专门研究了Neendakara-Kayamkulam(NK)沿海带稀土开采活动造成的噪声污染,Kollam,喀拉拉邦,印度,一个富含钛铁矿的地区,金红石,硅线岩,锆石,和独居石。尽管已知噪声污染对环境和健康的影响,该地区关于其大小和来源的具体数据有限,以及缺乏针对稀土采矿作业的有效缓解策略。研究表明,采矿作业,比如重矿物砂的移动,大大提高了噪音水平,这对环境质量和公众健康有影响。这项研究旨在通过地理空间制图和评估噪声水平来填补这一空白,并建议有效减轻噪声污染的措施。在NK沿海带内的48个合适位置进行了系统噪声测量,包括住宅,商业,工业,沿海,和沉默区。噪音水平从宗教场所附近的49.1dB(A)到当地工业附近的82.4dB(A)不等。该研究采用地理空间噪声映射和土地覆盖叠加来实施针对沿海附近混合土地利用区噪声污染的特定类别缓解措施,包括自然和植物障碍,运营调度,分区,和土地利用规划。
Noise pollution is an unintentional consequence of mining activities, needing rigorous assessment, monitoring, and mitigation techniques to reduce its impact on local residents and ecosystems. The study specifically examines the noise pollution from rare earth mining activities in the Neendakara-Kayamkulam (NK) coastal belt, Kollam, Kerala, India, a region rich in ilmenite, rutile, sillimanite, zircon, and monazite. Despite the known environmental and health impacts of noise pollution, there is limited specific data on its magnitude and sources in this region, as well as a lack of effective mitigation strategies tailored to rare earth mining operations. Studies have indicated that mining operations, such as the movement of heavy mineral sands, considerably elevate noise levels, which have an effect on the environment\'s quality and public health. This study seeks to fill the gap by geospatial mapping and assessing the noise levels and recommend measures to effectively mitigate noise pollution. Systematic noise measurements were conducted at 48 suitable locations within the NK coastal belt, including residential, commercial, industrial, coastal, and silence zones. The noise levels vary from 49.1 dB(A) near a religious place to 82.4 dB(A) near the local industry. The study employs geospatial noise mapping and land cover superimposition to implement class-specific mitigation measures for noise pollution in a coastal vicinity mixed land use area, including natural and vegetative barriers, operational scheduling, zoning, and land use planning.
