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.
