Abstract

Mine closure is an essential phase in mining, generating large investments without good planning. The use of mine closure guidelines assists in the creation of an effective mine closure plan, integrating all stakeholders: business, community and government, so that the end result is lasting and sustainable. Currently the concept of sustainability is widely discussed and this includes the mineral sector which is primordial in society as it acts as a basis in most industrial segments, playing an important role in the economy both as a generator of jobs and taxes as well as in the development of cities. and regions. By operating and closing a mine in compliance with the guidelines, the company demonstrates suitability to the demands of environmental protection and social responsibility, contributing to sustainability. The work proposed a closure plan for future use of the company, where steps were established for this project which include the description, diagnosis and future use of the area, decommissioning and monitoring measures are suggested during and after the project's useful life and evaluation of closure type. Regarding the classification of the type of mine closure, it was initially considered as “premature closure” due to the temporary suspension of the operation, but after reevaluation studies the company decided to resume production and then to “Scheduled closure” according to the classification of the current Mine Closure methodology adopted.
