Abstract

The invention relates to a reclamation isolation structure of an acid waste rock dumping ground, which sequentially comprises a clay layer, an acid waste rock layer and a wrapping layer from bottom to top; the wrapping layer completely wraps the acidic waste stone layer, and the wrapping layer sequentially comprises a benign waste stone layer, a clay layer, a drainage layer and a surface soil layer from inside to outside. The utility model discloses utilize the clay layer prevention of seepage, lead drainage layer protection clay layer not fracture, the topsoil layer reduces structure soil erosion and water loss, through multistage prevention of seepage and protection, avoids water and air admission acid barren rock layer, produces environmental pollution.

Description

Reclamation isolation structure for acidic waste stone dumping ground

Technical Field

The utility model belongs to the technical field of the mine operation, concretely relates to reclamation isolation structure of acid waste rock refuse dump.

Background

The acidic waste rocks generated in the process of mine operation are generally covered by the floating soil after being directly piled up, and generate acidic waste water after contacting with water and air, wherein the acidic waste water contains a large amount of dissolved metal ions and other harmful inorganic anions, so that the environment is easily polluted and the human body is easily damaged.

SUMMERY OF THE UTILITY MODEL

The utility model provides a reclamation isolation structure of acid waste rock refuse dump, the technical problem that solve is: solves the problem of environmental pollution caused by acidic waste rocks.

In order to solve the technical problem, the utility model provides an acid waste rock refuse dump reclamation isolation structure, its characterized in that: a clay layer, an acid waste stone layer and a wrapping layer are sequentially arranged from the bottom to the top; the wrapping layer completely wraps the acidic waste stone layer, and the wrapping layer sequentially comprises a benign waste stone layer, a clay layer, a drainage layer and a surface soil layer from inside to outside.

Has the advantages that: the utility model discloses utilize the clay layer prevention of seepage, lead drainage layer protection clay layer not fracture, the topsoil layer reduces structure soil erosion and water loss, through multistage prevention of seepage and protection, avoids water and air admission acid barren rock layer, produces environmental pollution.

Detailed Description

In order to make the objects, contents and advantages of the present invention clearer, the following description will be made in further detail with respect to the embodiments of the present invention.

The utility model provides a reclamation isolation structure of an acid waste rock dumping ground, which comprises a clay layer 1, an acid waste rock layer 2 and a wrapping layer from the bottom to the top in sequence;

the acid waste rock layer is completely wrapped by the wrapping layer, and the wrapping layer sequentially comprises a benign waste rock layer 3, a clay layer 4, a drainage guide layer 5 and a surface soil layer 6 from inside to outside;

performing first bottom seepage control on the clay layer 1; the acid waste stone layer 2 is a covered structure; the benign waste stone layer 3 is used for preventing seepage at the top of the second channel; the clay layer 4 is a third seepage-proofing layer at the top; the drainage layer 5 is used for preventing the clay layer from being dried and cracked in dry seasons, and can quickly drain water in rainy seasons; and the topsoil layer 6 is used for covering vegetation and reducing water and soil loss.

The drainage layer is made of sandstone or benign waste stone; the sandstone is used as the material of the drainage layer, has the best effect, but has higher cost; the method adopts benign waste rocks which exist in a large amount in the mining process as the material of the water guide and drainage layer, can effectively reduce the cost, and simultaneously increases a discharge and removal part of the benign waste rocks.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.

Claims
