Description
Technical field
The present invention relates to stone pit castaway slag soil resourceization to utilize field, is specifically a kind of stone pit castaway slag soil resource
Application way.
Background technology
Stone pit dregs：Refer to caused dregs in the work progress such as quarry blast excavation, hand excavation.
Dregs processing mode：The major way of China's disposal dregs is to select low-lying land, wasteland to carry out air storage, no
Substantial amounts of soil has been only taken up, the contradiction having a large population and a few land, and contaminated soil, water body and air has been exacerbated, influences city scape
See.It is the huge waste of resource by above-mentioned as it can be seen that dregs direct utility value in stone pit is low.Dregs accumulation to mining area landscape,
Land resource, water environment, bio-diversity etc. have an immense impact on, or even jeopardize existence and health, the influence area of the mankind
Economic sustainable development.
For many years, due to the unreasonable exploitation of mineral resources, plus extensive management, lack and plan, not only cause the huge of resource
It is big to waste, and the local ecological environment of heavy damage.Winter-spring season, wind play sand and raise, and abandoned mine provides for dust and sand weather
Material source.To rainy season, since vegetation is exposed, soil fail, soil erosion aggravates, and is easier to trigger landslide, landslide etc.
Natural geologic hazard.
In the prior art, generally afforested using direct earthing, yet with soil is of high cost, haul distance is remote, cause to plant
It is resumed afforestation of high cost, conventional and is not reaching to the day that sustainable vegetation recovers, causes plant percent not high.Together
When substantial amounts of dregs be not utilized, cause the wasting of resources.
