磷石膏尾矿库是以磷石膏渣堆积起来形成的尾矿库,其安全问题一直是磷化工企业及安全生产管理部门非常关心的问题。根据《尾矿库安全监督管理规定》,尾矿库工程在设计阶段应该编写安全专篇,需要对尾矿库及尾矿坝稳定性、尾矿库防洪能力及排洪设施和安全观测设施的可靠性进行充分论证。3个方面的内容紧密联系,其是否安全可靠决定着尾矿库是否安全运行。针对磷石膏尾矿库的安全专篇问题,分析了专篇中的关键技术内容,对防洪计算、稳定性计算和安全监测分析等方面的本质问题进行了探讨,并将这三者作为一个系统进行分析总结。通过对湖北某磷石膏尾矿工程安全专篇的编写与分析,对具体的技术方法给出了说明。目前尾矿库工程安全问题受到了广泛的关注,其结果提供了比较完整的具体经验,采用的方法和得出的结论对相关工程可以起一定的借鉴作用。 The phosphogypsum tailing pond is a tailing pond formed by accumulation of phosphogypsum slag. The safety issue has always been a great concern to the phosphorus chemical enterprises and safety production management departments. According to “Provisions on Safety Supervision and Management of Tailings Reservoirs”, the tailings dam project should be compiled with a safety monograph in the design phase. The stability of tailings ponds and tailings dams, the flood control capability of tailings ponds, flood control facilities and safety observation facilities Reliability is fully demonstrated. Three aspects of the content are closely linked, whether it is safe and reliable tailings dam is safe to run. Aiming at the safety issue of phosphogypsum tailing pond, the paper analyzes the key technical contents of the special articles, discusses the essential problems of flood control calculation, stability calculation and safety monitoring analysis, and takes the three as a system Analyze and summarize. Based on the compilation and analysis of a special piece of phosphogypsum tailing safety project in Hubei Province, the paper gives a description of the specific technical methods. At present, the safety of tailings dam project has received widespread attention. The results provide relatively complete and specific experience. The methods and conclusions drawn can play a certain reference role for related projects.
