The coal mining industry plays a vital role in Indonesia’s economy through export activities and domestic energy supply. However, it faces high risks due to fluctuations in commodity prices and global policy changes. This study aims to analyze the bankruptcy risk of coal mining companies in Indonesia using the Zmijewski and Taffler prediction models. The research employs a quantitative approach utilizing secondary data from the financial statements of coal mining companies listed on the Indonesia Stock Exchange. The findings are expected to provide a comparison of the accuracy and consistency of both models in predicting bankruptcy risk, as well as serve as a reference for stakeholders in assessing the financial stability of the coal mining sector. Keywords: bankruptcy risk, coal mining, Zmijewski model, Taffler model.
