including the stability of surrounding mountains and dangerous behaviors such as illegal construction, operation, tailings reuse, water withdrawal, waste discharge, grazing and reclamation.
including deformation, displacement, break, clogging, and drainage capability.
including contour, size, deformation, displacement, cracks, landslides, phreatic line, infiltration, etc.
Conduct flood calculation before flood season every year and set flood control plans. Ensure that TSF indicators accord with the requirements. Carry out an emergency drill before flood season. Conduct regular quality inspection of drainage structure.
Monitor infiltration, seepage, swampiness of TSFs. Observe and record the phreatic line during the operation of TSFs. Take measures and add seepage facilities when the phreatic line exceeds the threshold.
Conduct daily safety inspection and reinforce TSFs according to the highest TSF seismic design standards. Set emergency preparedness plans. Before earthquake, pay attention to the stability of embankment and prevent landslide. After the earthquake, emergency plans should be launched to comprehensively inspect the dam, drainage structure and flood control design. The damaged facilities should be repaired in time.
