在对中国五矿集团所属地下矿山松石冒落事故案例统计分析的基础上,结合具体实例分析,系统研究松石冒落的影响因素,探讨金属矿山松石冒落事故的发生机理,并对巷道围岩松动圈的形成和扩展进行数值模拟。提出预防松石冒落事故的相关技术和管理措施,具有较强的实用性,对类似金属矿山企业的安全管理具有指导意义。
Based on the statistical analysis of the case of mine collapsible falling underground mine owned by China Minmetals Corporation and the analysis of specific examples, the influential factors of turquoise fall were systematically studied, and the occurrence mechanism of the plunge of metal mine turquoise was discussed. The formation and expansion of loose rings were numerically simulated. The paper puts forward the related technologies and management measures to prevent the pine falling from the ground, which is of strong practicability and instructive for the safety management of similar metal mines.
