Embodiment Construction

[0018] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. As a part of this specification, the principles of the present invention will be described through examples. Other aspects, features and advantages of the present invention will become clear through the detailed description.

[0019] The experimental site is located in the mining pit test base of the West Open-pit Mine in Fushun City, Liaoning Province. In 2009, the ecological restoration method of the abandoned bare land in the open-pit coal mine area was adopted to carry out rock classification and sorting and soil reconstruction on the abandoned bare land in the open-pit mine area. And plant torch tree, locust tree, elm, peach, poplar, spirea, water wax and some herbs. The herb community refers to the mixed community of Jerusalem artichoke, Artemisia mongolica, and Liaodong zoysia. Coarse aggregates such as gravel and sand are measured ...

Abstract

The invention discloses an opencut coal mine abandoned bare land ecological remediation method, comprising bare land habitat ecological remediation work, vegetation ecological restoration work and enclosure governing. The bare land habitat ecological remediation work includes arranging and classifying abandoned aggregate, cement blocks and gravel sand in a mining area according to grain size, utilizing the abandoned cement blocks and bricks to build pavement, stacking other aggregate from bottom to top from large to small, and finally filling gaps of gravel with fine gravel sand; the vegetation ecological restoration work includes performing community investigation to the surrounding of the coal mine, selecting suitable local tree species and planting the tree species, and planting vine plants at the slope toe. By means of using local materials, namely, by directly utilizing the abandoned aggregate, cement blocks and gravel sand to create a habitat environment suitable for natural survival of plants, cost for ecological remediation is reduced, and ecological remediation efficiency is increased.

Description

technical field [0001] The invention relates to an ecological restoration technology for abandoned bare land in an open-pit coal mine area, in particular to a method for artificially inducing natural ecological restoration and vegetation reconstruction in an open-pit coal mine area. Background technique [0002] China is a country rich in mineral resources, and mineral resources have made significant contributions to social and economic development for a long time. At the same time, the long-term large-scale and disorderly mining of human beings has not only left a large number of abandoned mining areas, but also brought extremely serious damage to the surrounding ecological environment. Before and after mining, the landscape presented by the mining area is quite different. Before mining, the local ecosystem has normal protection and production functions, and is in a relatively stable state; after mining, the stability of the ecosystem in the mining area will be severely da...
