Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing.

[0027] like figure 1 as shown,

[0028] The structure of the dry-type discharge tailings sand foundation impermeable dam of the present invention includes the original tailings sand dam body foundation 11, and is characterized in that:

[0029] 1) On the basis of the original tailings sand dam body 11, the rock-discharging dam main body 9 is filled, and the rock-discharging dam main body 9 is composed of a protective slope inside the dam body reservoir and an outer slope 10 outside the dam body reservoir. Formed with horizontal dam crest 8, the protective slope inside the dam body storehouse is a stepped protective slope, and the described stepped protective slope is composed of the lower section 2 of the inner slope in the storehouse, the upper section 6 of the inner slope in the storehouse and the inner slope with the described storehouse. The horizontal horseway 5 ...

Abstract

The invention relates to a structure and a constructing method of an impermeable dam provided with a dry type tailing sand discharging base. The structure comprises an original tailing sand base, and is characterized in that a rock-dumping and damming body is filled on the original tailing sand base and comprises a protective slope on the inner side of a dam body reservoir, an outer reservoir slope on the outside of the dam body reservoir and a horizontal dam crest, wherein the protective slope comprises an inner protective slope lower segment, an inner protective slope upper segment and a horizontal bench arranged between the inner protective slope lower segment and the inner protective slope upper segment; the inner protective slope lower segment is connected with a tailing sand operating pit slope; and impermeable elements are laid on the protective slope on the inner side of the dam body reservoir and the tailing sand operating pit slope and covered with tailing sand layers. The structure and the constructing method have the advantages as follows: the impermeable dam provided with the dry type tailing sand discharging base and the structure is adopted, so that the structure is waterproof and firm; and local rock-dumping materials are fully utilized, so that the damming cost can be greatly reduced and the benefit is very considerable.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, in particular to a structure and a masonry method for an impermeable dam based on dry tailings sand discharge. Background technique [0002] Tailings pool refers to the place where dams are built to intercept valley mouths or enclosures, and are used to stockpile metal or non-metal mines for ore sorting and then discharge tailings or other industrial waste. Existing tailings ponds refer to existing tailings ponds that have already been formed. Tailings dry discharge is a new tailings disposal technology that has gradually emerged in China in recent years. Its rise is mainly due to the fact that the existing tailings ponds of various mining companies adopt wet discharge methods (wet discharge methods are tailings in slurry Under normal conditions, the tailings are sent from the concentrator to the tailings pond through the pipeline, the tailings in the slurry are deposit...
