Mexico's mining market value in 2022 was USD 3.3 billion. About half of Mexico's mining production consists of the extraction of precious metals, with the remaining output composed of 40 percent non-ferrous, six percent metallurgy, and seven percent non-metallic ores. In 2022, production in mining reached USD 16.16 billion.
elements of the coal mining process, which included two fuzzy systems: re safety evaluation system (FSES) and functional safety over EtherCAT (FSOE). The FSES per-forms equipment selection to support long-walled working faces, whereas FSOE supports estimations of the production results. The equipment selection results are obtained based
