Justification of reclamation parameters for lands disturbed during the development of gold placers

Abstract

The article deals with the issue of reclamation of lands disturbed during the development of gold placers. Using the results of surveys and studies of the rocks composing the surface layer, the authors compare the present state of disturbed lands and the technogenic relief designed by technical documents on the development of alluvial placers. The discrepancy between actual and design data is analyzed. The conditions of natural vegetation restoration are studied. Results of observations of the natural vegetation restoration within loose deposits are presented. Recommendations on flattening angles depending on the length of slopes and elevation differences between the bottom and crest of technogenic embankments are given. The design results for reclamation of disturbed lands based on preliminary surveys and mining project data are compared. Methods for reducing the amount of reclamation works are substantiated.

Improvement of quarry and slagheap reclamation technology

“…The study focuses on the view that there are no clear requirements for the reclamation and alignment of anthropogenic relief. This generally complicates the processing of sloped land plots [16]. The paper investigates the influence of slope angles, quarry depth, and other characteristics of degraded landscapes on the choice of land reclamation methods.…”
