Problems solved by technology

For example, a method (CN101632993B) and a new tailings dam construction technology (CN202830941U) using mine excavation to pile up tailings dams. Although these methods have the characteristics of saving construction costs or preventing waterlogging, they still have disadvantages The long-term operation of the mine depot, the structure is unstable, and it is easy to cause safety problems, pollute the soil, and have serious consequences.

Embodiment 1

[0046] The construction method of the tailings dam flexible damping system includes the following steps:

[0047] S1. First, flatten and reinforce the foundation and embed support columns 8 so that the support columns 8 are evenly distributed in the tailings dam area, and then lay the first layer of anti-seepage steel plates 9 on the support columns 8, and then lay the first layer of anti-seepage steel plates Install the shock absorbing support 4 on the 9, and the support column 8 corresponds to the shock absorbing support 4 one by one, and then lay the second layer of anti-seepage steel plate 10 on the shock absorbing support 4;

[0048] S2. On the second layer of anti-seepage steel plate 10, establish the initial dam 1 and the downstream retaining dike 3 according to the centerline method. into the permeable reaction wall 5, and connect the seepage drainage pipe 6 of the initial dam 1, the seepage drainage pipe 6 of the downstream retaining embankment 3, and the permeable re...

Embodiment 2

[0051] The construction method of the tailings dam flexible damping system includes the following steps:

[0052] S1. First level and reinforce the foundation and embed support columns 8 so that the support columns 8 are evenly distributed in the tailings dam area. The diameter of the support columns 8 is 50 cm and the height is 3 m. The distance between them is 1.5m, and the height difference between two adjacent support columns 8 is less than 0.5mm. Then the first layer of anti-seepage steel plate 9 is laid on the support column 8, and then the shock-absorbing support 4 is installed on the first layer of anti-seepage steel plate 9. , and the support column 8 corresponds to the shock absorber 4 one by one, and then the second layer of anti-seepage steel plate 10 is laid on the shock absorber 4;

[0053] S2. On the second layer of anti-seepage steel plate 10, establish the initial dam 1 and the downstream retaining dike 3 according to the centerline method. into the permeable...

Embodiment 3

[0056] The construction method of the tailings dam flexible damping system includes the following steps:

[0057] S1. First level and reinforce the foundation and embed support columns 8 so that the support columns 8 are evenly distributed in the tailings dam area. The diameter of the support columns 8 is 100 cm and the height is 5 m. The distance between them is 2.5m, and the height difference between two adjacent support columns 8 is less than 0.5mm. Then the first layer of anti-seepage steel plate 9 is laid on the support column 8, and then the shock-absorbing support 4 is installed on the first layer of anti-seepage steel plate 9. , and the support column 8 corresponds to the shock absorber 4 one by one, and then the second layer of anti-seepage steel plate 10 is laid on the shock absorber 4;

[0058] S2. On the second layer of anti-seepage steel plate 10, establish the initial dam 1 and the downstream retaining dike 3 according to the centerline method. into the permeabl...

Abstract

The invention discloses a high-stability tailings dam and a construction method thereof. The high-stability tailings dam includes an initial dam, a toe dam, a downstream retaining embankment, a shock-absorbing support, a permeable reaction wall, and a seepage drainage pipe. The high-stability tailings dam of the invention is beneficial to reducing the harm of discharged waste water to the downstream environment, reducing the wetting line of the tailings dam, reducing the erosion of waste liquid on the dam body, and maintaining the stability of the dam body. The construction method of the high-stability tailings dam includes foundation treatment, establishment of an initial dam, a downstream retaining embankment and a toe dam. The construction method of the invention keeps the building stable, which is beneficial to the safe and long-term operation of the tailings dam.

Description

technical field [0001] The invention belongs to the technical field of water conservancy facilities, and in particular relates to a tailings dam with high stability and a construction method thereof. Background technique [0002] Tailings pond is one of the three major control projects in mines, and it is also a major source of danger in mines. There are a large number of tailing ponds in my country and the conditions are poor. In recent years, a series of tailing pond accidents have occurred, which have threatened people's property, personal safety and ecological environment. my country is an earthquake-prone country, and tailings dams are almost permanent buildings. Therefore, the safety and stability of tailings dams are very important and have become a major concern of governments, mining companies, and academic circles. The commonly used construction methods now mainly use the natural terrain to build upstream tailings dams and bury seepage pipes. The advantage is that...
