Phosphogypsum dregs are piled together to form phosphogypsum tailings pond. Phosphorus chemical enterprises and management departments are very concerned its safety issue. According to the Supervision and Management of Tailings Dams Safety Regulations
China
in the design stage of a tailings project
security specific report should be prepared
in which the stability of the tailings and tailings dam
the control capacity of flood and the reliability of the drainage and safety observation facilities should be fully evaluated. Three aspects link closely
which determine the safety of tailings operation. The key technical contents of the safety specific report are analyzed. The essences of calculation of flood control
stability as well as safety monitoring are discussed; and the three aspects are analyzed as a system. Through the compilation and analysis of a safety specific report of a phosphogypsum tailings project in Hubei province
the specific technical instructions are given. As a matter of great concern at present
the paper provides a more complete specific experience for safety analysis of tailings. The methods and conclusions can play a certain reference to the related projects.
