7.5 Operating procedures
7.5.1 Before the flood season, flood discharge and drainage facilities must be comprehensive, especially the key parts such as inlet and outlet, which should be repeatedly inspected and found to be promptly disposed of;
7.5.2 Prepare necessary rescue materials, tools and equipment. Maintenance and refurbishment of roads leading to the tailings pond and roads on the dam, and ensuring safety and smoothness;
7.5.3 Strengthen the duty and inspection, the flood discharge (water) port must be guarded by special personnel, closely monitor the water regime change of the reservoir and the surface runoff dynamics of the gully on both sides of the dam, report the dangerous situation in time, and take urgent measures to prevent the situation from deteriorating. Leading to a broken top dam;
7.5.4 Calculate the maximum flood level and water edge position of the reservoir in the flood season according to the storage capacity, the catchment area, the flood season and the discharge capacity, and combine the ultra-high and sedimentary beach length, slope and slope shape required for safety. In case of slope seepage, etc., comprehensive consideration should be given to formulating a safe ferry scheme for tailings ponds, and if necessary, appropriate safe and reliable emergency flood discharge measures should be taken to prevent problems before they occur;
7.5.5 Open the water inlet above the normal water level of the flood discharge (water) structure to a certain height, and if necessary, reduce the water storage line must be unimpeded and fully exert the flood discharge efficiency;
7.5.6 A conspicuous, clear and secure water level observation scale shall be set up in the library and linked to the absolute elevation;
7.5.7 After the flood, the dam body and the flood discharge (water) structure pipe trenches and weak links shall be carefully inspected and cleaned. If problems are found, they shall be repaired or reinforced in time, and the tailings pond shall be kept at a high water level as much as possible. Free up the storage capacity and prevent floods from coming.
