Abstract:This paper is grounded in the context of the new national energy security strategy and the moderniza-tion of coal mine safety governance system.It is based on the measured data from Guizhou Province in the past five years,then systematically analyzes the core geological control mechanisms and spatiotemporal distribution patterns of gas occurrence,and elaborate on the current situation of prominent identification work in Guizhou.The research indicates that Guizhou's tectonic stress field is complex,with large-scale fold and fault systems exerting a dominant control over gas enrichment and accumulation.A high degree of coupling exists between zones of tectonic stress concentration and anomalous zones of gas pressure and content.The central high-meta-morphic anthracite region,due to its superior hydrocarbon generation and reservoir-cap rock assemblages,re-presents the province's peak gas content zone and a key focus for disaster management.Statistical data show that the number of mines(or instances)identified with outburst risks in Guizhou accounts for 31.7%of the national total,highlighting the arduous nature of outburst prevention tasks.The current prominent identification work faces three major contradictions:the conflict between universal national standards and strong regional geo-logical heterogeneity;the conflict between a static,discrete identification model and the dynamic,continuous evolution of disaster risk;and the conflict between the lag in identification work and the need for synchronous,high-efficiency mine construction.Finally,from the perspectives of top-level design,technological innovation,and regulatory model,this paper proposes the construction of an elastic technical standard system based on risk assessment,establishing a dynamic risk assessment mechanism that spans the entire mine life cycle,and the in-troduction of a blockchain-based regulatory mechanism for the first time.
