Strip mine waste dump platform soil reconstruction method based on mound embedding structures

Abstract

The invention discloses a strip mine waste dump platform soil reconstruction method based on mound embedding structures. The strip mine waste dump platform soil reconstruction method includes the steps of 1, mound embedding structure type selecting and layout designing, wherein the type of the mound embedding structures is selected according to vegetation recovery requirements of a waste dump platform, the layout of the mound embedding structures on the waste dump platform is designed in cooperation with the loading capacity M of stacking dumpers, the mound embedding structures are triangular mound embedding structures based on plane mound embedding or regular-polygon mound embedding structures based on plane mound embedding or regular-triangle mound embedding structures based on vertical mound embedding or square embedding mound structures based on vertical mound embedding; 2, mound embedding structure stacking; 3, vegetation planting region leveling, wherein vegetation planting region leveling is carried out on the stacked mound embedding structures. The method is simple in step, reasonable in design, convenient to achieve and good in use effect, soil beneficial for vegetation recovery can be easily and conveniently reconstructed on the waste dump platform, water and soil losses can be reduced, and the waste-dump ecological environment can be effectively managed.

Description

technical field [0001] The invention belongs to the technical field of dump site treatment, and in particular relates to a soil reconstruction method for an open-pit mine dump site platform based on a pile structure. Background technique [0002] Surface mining is one of the important forms of mineral resource extraction. The ecological environment of open-pit mining is severely damaged, and ecological restoration is difficult, requiring in-depth research from all levels. Dump site, also known as waste rock site, refers to the place where mining waste is discharged intensively. The waste mainly includes humus topsoil, weathered rock and soil, hard rock and mixed rock and soil, and also includes surface ore that may be recovered, poor Mine etc. The dump site is an unavoidable environmental problem in the open-pit mining of mineral resources, and the effective management of the dump site has become an important aspect of environmental governance. Many domestic researchers h...

Problems solved by technology

[0003] But at present, there are two deficiencies in the treatment of dump sites: first, the dumping is random, and there is no reasonable design according to the follow-up vegetation restoration requirements; second, the mixture of raw soil and topsoil in the pile is not conducive to the growth of vegetation; 3. The soil reconstruction process was not designed according to parameters such as the needs of vegetation restoration and the loading capacity of on-site construction machinery
