This study investigated the construction pathway of the overall safety and emergency response framework by strengthening its theoretical connections with industrial safety governance. Focusing on the mining industry, this study conducted discourse analysis on mine work safety policies using ROST CM6 software. Through six chronological phases, lexical cluster statistics and semantic network mapping were systematically performed to reveal the evolutionary trajectory of policy discourse. The results show that three discourse paradigms of "safety", "emergency" and "risk" exhibit diachronic iteration, which respectively realize the functions of policy continuity, domain expansion and theoretical innovation. These paradigms synergistically integrate through functional complementarity, ultimately forming a unified discourse system centered on comprehensive safety and emergency governance. The research validates the theoretical logic underlying the framework's formation and highlights its significance in deepening disciplinary connotation and advancing interdisciplinary boundaries.
