Abstract
Nickel ore resources in Southwest China are primarily distributed in provinces such as Yunnan,Sichuan,and Guizhou,dominated by sulfide nickel ores and laterite nickel ores,with reserves accounting for more than 10%of the national total.However,the ore bodies are mostly vein-like or bedded in distribution,accompanied by associated metals such as copper and cobalt,featuring complex geological conditions and increasingly deepening mining depths.The current mining status is mainly underground mining,with an annual output accounting for approximately 15%of the national total.Nevertheless,it is constrained by factors including high in-situ stress,easy accumulation of gas,and harsh hydrological conditions,resulting in frequent safety accidents and hindering efficient resource utilization.The research content of this paper includes analysis of geology and mining conditions in typical nickel mining areas in Southwest China,assessment of major safety risks,development of key technologies for safe mining,and applications of intelligent monitoring.Through this study,a replicable safety technology framework can be provided for nickel mining areas in Southwest China,promoting the sustainable development of the regional mining industry.关键词
