Due to the large proportion of accidents that occurred in Minas Gerais involving dams for the accumulation of mining tailings, Mariana (2015) and Brumadinho (2019) respectively, through legal instruments, the state has sought a level of maturity in terms of management of dams with the aim of eradicating accidents of these proportions. Therefore, currently, obtaining or renewing installation and operation licenses in the state of Minas is linked to formal approval by the competent PAEBM body. Many requirements have been published to guide the preparation, review and approval of this extensive and complex document. The accurate and impartial evaluation of documents in the state is, therefore, an immeasurable challenge, given the amount of information generated and the various areas that permeate the objective of the PAEBM in compliance with the State Policy on Dam Safety. This work aims to present guidelines that make it possible to technically assist the control bodies in the analysis of Emergency Action Plans for Mining Dams ("PAEBM") in accordance with Resolution No. 95, of February 7, 2022, which consolidates the normative acts that provide for the safety of mining dams, as well as other complementary and specific ones, such as the State Policy on Dam Safety - Law. 23,291 of February 25, 2019. To this end, it is intended to develop and apply methodology developed in the research in a real case study of a dam located in the Iron Quadrangle of Minas Gerais, pointing out opportunities for improvement.
