Royalties from Financial Compensation for Mineral Resources Exploitation (CFEM) aim to mitigate negative impacts on mining regions. Legislation does not specify how the resources should be applied. The objective of this study was to link CFEM distribution and environmental variables to the mining municipalities of Minas Gerais State, Brazil, and to verify if these resources help mitigating negative environmental impacts caused by mining activity. Area of Conservation Units (CU), category of CU and jurisdiction of CU of Minas Gerais mining municipalities and investment in environmental conservation were the environmental variables related to CFEM value. Land use maps of the municipalities between the years 2006 and 2016 were evaluated. Pearson's correlation coefficient was used for correlating the forest areas with the CFEM values received. More than half of the mining municipalities do not present CU, which shows that the mining activity does not stimulate the implementation of the CU. In addition, the implementation of the CU presents financial, human resources and land tenure barriers. However, these barriers cannot make invisible the positive externalities provided by the existence of well-managed MCU. Three major mining municipalities with Municipal Conservation Units (MCU) invested 4.02%, 1.82% and 1.88% of CFEM in environmental conservation, demonstrating an inadequate resources application. The land use maps and the correlation graphs show that there is no significant correlation between the receipt of CFEM and the increase in forest areas in the municipalities. CFEM does not help mitigate negative environmental impacts of mining. One of our suggestions is that the mining municipalities invest the CFEM resource obtained in maintaining existing CU and in creating and implementing new CU in their territories.

矿产资源开发金融补偿费（CFEM）旨在减轻对矿区的负面影响。立法没有规定应如何使用资源。这项研究的目的是将CFEM分布和环境变量与巴西米纳斯吉拉斯州的采矿市镇联系起来，并验证这些资源是否有助于减轻采矿活动对环境的负面影响。米纳斯吉拉斯州矿业城市的保护单位面积（CU），CU的类别和CU的管辖范围以及环境保护投资是与CFEM值相关的环境变量。评估了2006年至2016年之间市政当局的土地使用图。皮尔逊相关系数用于将森林面积与接收到的CFEM值相关。超过一半的矿业城市没有CU，这表明采矿活动不会刺激CU的实施。此外，CU的实施还带来了财务，人力资源和土地使用权障碍。但是，这些障碍不能使管理良好的MCU所提供的积极外部性无形。拥有市政保护单位（MCU）的三个主要矿业城市在环境保护方面投资了CFEM的4.02％，1.82％和1.88％，表明资源利用不足。土地利用图和相关图表明，在城市中，CFEM的接收与森林面积的增加之间没有显着的相关性。CFEM无助于减轻采矿的负面环境影响。
