Adverse-slope flat-plate treating and ecological restorative measure for refuse dump

Abstract

The invention discloses an adverse-slope flat-plate treating and ecological restorative measure for refuse dump, which comprehensively optimizes and determines gradient, length of grade and width of flat plate of a refuse dump according to experiences, calculations and land using characters; slope cutting grades of accumulation slope of the refuse dump are designed into three grades, each grade of slope height is 9-11 m, the width of the slope flat plate is 4-6 m; the following slope ratios are included: the first grade is 1: (1.9-2.1), the second grade is 1: (1.7-1.8), and the third grade is 1: (1.4-1.60); the flat plate is treated into adverse slope type, the flat plate is leant toward the inner side slightly, and the adverse slope is in 2-5 degrees; the first and the second grades of slopes use masonry arch centers for planting grass, apron on base of slope, masonry slop flat plate and drainage ditch thereof, slope surface edge for designing and constructing; the third grade of slope applies vetiver revetment afforesting technique; Bahia grass is planted in the flat plate of the refuse dump firstly, for covering the flat plate and conserving water and soil in a short time via the characters of fast growing and barren resistance; and then fruit trees or crops are planted in the flat plate. The method takes engineering measures and biological measures comprehensively for guaranteeing safety of mine dump and achieving good ecological restoring effect and view result, and plants which adjust measures to local conditions are planted, and the cost is low.

Description

technical field [0001] The invention relates to an ecological restoration technology of mine wasteland, in particular to a technique and a measure for flattening and ecological restoration of a mine dump. Background technique [0002] Over the past 30 years, mining development has occupied and destroyed a large amount of land, causing disasters such as ground subsidence, landslides, mudslides, and serious pollution, which has attracted widespread attention and has become a restrictive factor affecting the harmonious development of society. [0003] With the rapid development of my country's economy, the demand for industrial raw materials and energy is increasing, and the mining of mineral resources is becoming more and more frequent. Mining mining will inevitably cause certain damage to the ecological environment, and the resulting environmental pollution and ecological damage are particularly prominent. , which is one of the most important issues that people are currently p...

Problems solved by technology

[0007] At present, the relatively large waste dump ecological restoration technology, the traditional method is that the slope is completely planted with grass on the masonry arch, mainly based on engineering measures, and the grass species are mainly local weeds, the project cost is high, and the ecological restoration effect is poor. , it is difficult to achieve the purpose of improving and restoring the ecological environment and restoring the regional landscape
