Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as Figure 1-4 As shown, the reference signs are: osmometer 1, air compressor 2, inflatable pipe 3, anode electrode 4, cathode drain pipe 5, initial infiltration line 6, infiltration line after inflation and water interception 7, sub-dam 8, initial dam 9. Hole 301, iron cover 302, magnet 303.

[0026] The inflatable water interception and seepage reduction system for quickly lowering the infiltration line in the tailings pond consists of a monitoring and early warning system, an aeration system, and a drainage system.

[0027] The monitoring and early warning system consists of a piezometer 1 or piezometric tube embedded in the tailings pond and a microcomputer processing system. Wireless transmission to the microcomputer control system, the microcomputer control system compares the measured infiltration line data with the preset ...

Abstract

The invention discloses an inflatable water-interception seepage reducing system for quickly lowering the seepage line in a tailing pond, and belongs to the technical field of tailing dam seepage eliminating. The inflatable water-interception seepage reducing system comprises a monitoring early-warning system, an inflation system and a drainage system. The monitoring early-warning system comprisesan osmotic pressure meter or a piezometer tube buried in the tailing pond and a microcomputer processing system, and the microcomputer processing system is connected with the osmotic pressure meter or the piezometer tube and further connected with the inflation system and the drainage system; the inflation system comprises an air compressor and an inflation pipe; the drainage system comprises ananode electrode and a cathode drainage pipe. The invention further discloses an inflatable water-interception seepage reducing method for quickly lowering the seepage line in the tailing pond. The microcomputer processing system is utilized, the inflation system and the drainage system are automatically started at a proper moment according to the setting of the system, so that the manual responsetime is shortened, and the emergency efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of tailings dam seepage drainage, and in particular relates to an air-filled water interception and seepage reduction system and method for rapidly lowering the infiltration line in a tailings dam. Background technique [0002] my country has now become a large mining country, and the annual tailings discharge of 12 kinds of bulk minerals is about 300 million tons. , except for a small part as mine filling or comprehensive utilization, a considerable part of the tailings is stored by constructing tailings ponds. [0003] As one of the three major basic projects of mines, tailings ponds are also a major source of danger for metal and non-metal mines. Among the 93 hidden dangers of accidents and public hazards in the world, tailings pond accidents rank 18th. So far, there are more than 12,000 tailing ponds in my country, many of which are dangerous and sick. Since 2005, there have been more than 40 dam failur...
