Aspectos e impactos ambientais de mineração: o caso de pedreira no nordeste do estado do Paraná

Abstract

This work addresses the main issues related to mining in quarries in the State of Paraná. The study presents the applicable Brazilian legislation and the general environmental licensing guidelines for mining activities, with the aim of verifying the critical points of application of this specific legislation. Through the literature review, the conceptual aspects of environmental licensing for mining activities were addressed, contextualizing the transformations and evolution of the use of mineral resources in Brazil, highlighting the need to make economic development compatible with environmental sustainability. Data collection was carried out through a bibliographical review, as well as by analyzing the environmental licensing process for quarries in the state of Paraná. The research results highlighted several critical points related to mining activity, such as difficulties associated with the environmental management of mining plans, erosion control, management of so-called environmental liabilities, monitoring of noise and air pollution and finally neighborhood conflicts. Given these weaknesses, some solutions were suggested that promote the minimization of environmental impacts associated with mining in quarries. Based on this information, it can be concluded that the work provides a significant contribution to environmental licensing studies of mining enterprises in quarries in the state of Paraná. The research results, in addition to providing relevant information about the legal approach to these ventures, suggest a set of actions to promote environmentally sustainable development in this sector.
