Abstract

The invention provides a novel sandstone area mine reclamation seepage-control growth promotion technology and arrangement structure. Firstly, a seepage-control layer is arranged in a soil covering layer of a mine reclamation area, namely, a sandstone saprolite layer is backfilled with 10cm-40cm sandstone saprolite which is leveled and compacted, seepage-control composite solution with the concentration of 5%-10% is sprayed, the seepage-control composite solution and soil are solidified to form the 1cm-5cm seepage-control layer, and backfilling of 40cm-110cm sandstone saprolite is continued after the seepage-control layer is formed. Secondly, dominant microbial strains suitable for local environments are introduced into the soil covering layer, soil formation of sandstones is promoted by microbes, soil structures are improved, and plant growth is promoted. Finally, shrubs such as Chinese pines and wild apricots suitable for the local environments are planted, and herbaceous plants suchas alfalfa and astragalus adsurgens palls are spread. The problems of serious seepage, low vegetation survival rate, low vegetation cover area and the like of a mine reclamation area at the present stage are solved.

Description

technical field [0001] The invention belongs to the field of ecological restoration engineering, and in particular relates to a new type of coal mine reclamation control seepage control technology and an arrangement structure in the sandstone area. Background technique [0002] The arsenic sandstone area is located in the Ordos Plateau. The climate type is an arid and semi-arid transitional area. The landform type is also a transitional area from the Loess Plateau to the northwest desert type. The environmental heterogeneity is extremely prominent, the soil is barren, the vegetation is scarce, the vegetation is seriously degraded, and the soil erosion is severe. . [0003] The Pishayan area is rich in coal resources. Large coal fields such as Shenfu Dongsheng Coalfield and Zhungeer Coalfield are located in the Pishashayan area. The coal seams in this area are relatively shallow, and most of them are open-pit mining. Vegetation has caused serious damage. In the reclaimed ar...
