[Procedures] 554 After the non-work to help form a certain range of the boundary steps, the slope stability analysis and evaluation should be carried out regularly, and safety measures must be taken for unstable slopes that affect production safety.
Article 588 The management of slopes of dumps must comply with the following regulations:
(1) Regularly analyze the stability of the dump slope and take preventive measures when necessary.
(2) Before the construction of the internal dumping site, the shape of the basement, the occurrence state of the rock stratum and the physical and mechanical properties of the rock are ascertained, the mechanical parameters of the abandoned material are determined, the design of the dumping site and the calculation of the slope stability are carried out, and the removal of the substrate is not conducive to Soft rock with stable slope.
(3) There must be sufficient safety distance between the bottom of the lowermost step of the inner dump and the bottom of the mining step.
(4) The dump site must adopt effective water and drainage measures to prevent or reduce the flow of water into the dump.
[Execution Description] With the development of the stope and dumping site, the geological conditions of the mine are constantly changing, and the slope stability analysis and evaluation should be carried out at least once a year.
