Terms and definitions such as tailings pond (see Chapter 3); --- Revise the grading standards of the first-class tailing pond and the second-class tailing pond (see 4.5, 4.1 of AQ2006-2005); ---In the analysis method of the anti-sliding stability of the tailings dam slope, the simplified Bishop method and the corresponding minimum safety factor are added (see 5.3.16); ---Added relevant requirements for dynamic seismic calculation of tailings dams (see 5.3.17); ---Modified the flood control standard of tailing pond (see 5.4.1, 5.4.2 of AQ2006-2005); --- Deleted the content of "tailing pond safety" and "tailing pond utilization and reuse after tailing pond closure" (see Chapter 8 and Chapter 10 of AQ2006-2005); ---Added the content of "tailing pond mining" and "emergency management of production and business units" (see Chapter 7 and Chapter 10).
