Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0029] Such as Figure 1-3 As shown, the embodiment of the present invention provides a kind of fast dam building method of fine tailings and high-concentration unsorted tailings, comprising the steps:

[0030] S1, the grid skeleton of a layer of geocells is directly located on the front beach of the original dam;

[0031] S2, putting ore into the geocell until the geocell of the current layer is completely filled and consolidated;

[0032] S3, setting a layer of drainage facilities on the geotechnical form that is completely filled and consolidated,

[0033] S4, placing a new layer of geocell ...

Abstract

The invention discloses a quick damming method adopting fine-grained tailings and high-concentration non-separation tailings, and relates to the technical field of tailing pond construction. The damming method comprises the steps that a special geocell is adopted as a damming grid framework, combined with drainage facilities and hydraulic filling and ore drawing arrangement, the damming grid frameworks with different sizes are arranged in a dam in layers to form an integral three-dimensional network structure, and drainage pipe network systems with different intervals are arranged in the dam,so that fine-grained tailings are effectively drained and consolidated through the drainage facilities to form a dam structure with high stability; and in addition, the fine-grained tailings in a pondare used for damming, the transportation and use of additional damming materials are reduced, the project investment is effectively reduced, the use of materials, such as soil or waste rock, outsidethe pond is greatly saved, and land resources and the ecological environment are protected. Therefore, by adopting the quick damming method, the safe operation of the tailing pond is promoted, the damming efficiency is improved, and the energy is saved and the consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of tailings dam construction, in particular to a fast dam-building method for fine-grained tailings and high-concentration unsorted tailings. Background technique [0002] Tailings pond is an important part of mine engineering, which is used to store a large amount of waste slag generated during the mining process. As a dangerous source of man-made debris flow with high potential energy, the safe operation of tailings pond not only affects the economic benefits of mining enterprises, but also affects the safety of life and property of downstream residents in the reservoir area and the stability of the surrounding ecological environment. [0003] According to statistics, up to now, there are 7,793 tailings ponds in my country, of which more than 10% are fine-grained tailings ponds. Moreover, with the improvement of my country's mineral processing technology and the continuous improvement of the requirements ...
