Abstract

The invention discloses a method for preventing and treating tailing sand leakage in a tailing pond dam body. The method comprises the steps that data information of an inner slope of a tailing pond initial dam or the upstream of a tailing leakage position is collected; an inverted filter wall is arranged on the upstream of the inner slope of the initial dam of the tailing pond or the tailing leakage position; the compactness of the inverted filter wall is jointly detected; and data information of a seepage water body at the downstream of a water outlet of the tailing pond and cavity information of a dam body where the inverted filter wall is located are monitored, and setting information of the inverted filter wall is adjusted in time. According to the method for preventing and treating tailing sand leakage in the tailing pond dam body, hardware facilities such as the inverted filter wall are reasonably arranged according to local conditions and data information of the tailing pond dam body, the inverted filter capacity of the dam body is improved, and set parameters of the dam body are revealed; meanwhile, a dynamic monitoring method is provided, and measures and opportunities for crisis such as tailings pond leakage are adjusted in time; and finally, a prevention and treatment system for preventing tailing sand leakage in the tailing pond dam body is formed.

Description

technical field

[0001] The invention belongs to the technical field of controlling tailings sand leakage, and relates to a method for preventing and controlling tailings sand leakage in a dam body of a tailings pond. Background technique

[0002] As a storage place for solid waste discharged from mine concentrators, tailings ponds are key areas where disasters and accidents occur in mining enterprises. The tailings pond is divided into initial dams, accumulation dams, sedimentary shoals and other components, which are used to intercept and store tailings and other industrial waste. The tailings pond is a complex and changeable dynamic system, and there are many factors that can cause accidents such as secondary disasters in the tailings pond. In recent years, secondary disasters such as tailings sand leakage and dam breaks in tailings ponds have occurred from time to time, which greatly endanger the ecological environment and pose a major threat to people's lives, health an...
