Abandoned mine soil remediation method
The invention discloses an abandoned mine soil remediation method. The abandoned mine soil remediation method comprises the following steps of trimming a mine waste disposal site, trimming the top ofthe mine waste disposal site to be a flat region, and trimming the slope of the sloping surface of the mine waste disposal site until the slope is smaller than or equal to 45 degrees; performing deepploughing and drying on the flat region twice; plowing the plat region twice; every 31-41 days, repeatedly plowing the plat region twice until the covering rate of earth surface plant covers in the plat region exceeds 40%, plowing the flat region once again, and during plowing, burying biomass strip bags to soil once again; spraying soil which is thoroughly decomposed after being fermented, with grass seeds to the sloping surface of the mine waste disposal site; enabling a transition plant cover hanging device to be arranged at the jointed part of the flat region and the sloping surface; enabling a plurality of water storing plant cover blocks to be hung below a plant cover zone in rows; transplanting bushes on vacant lots between the water storing plant cover blocks in rows on the slopingsurface, and transplanting bushes on the flat region in rows. According to the abandoned mine soil remediation method, plant covering of the mine waste disposal site can be rapidly repaired, water and soil can be effectively held, and generation of natural disasters can be avoided.
本发明公开了一种废弃矿山土壤修复方法，包括以下步骤：修整矿山排土场，将矿山排土场的顶部修整为平台区，将矿山排土场的坡面坡度修整至坡度小于等于45度；深耕并晾晒平台区两次；翻耕平台区两次；每隔30‑40天，重复翻耕平台区两次，直至平台区地表植被覆盖率超过40％，之后，再次翻耕平台一次，翻耕同时再次向土壤中埋入生物质条袋；向矿山排土场的坡面喷洒带有草种的发酵腐熟土壤；在平台区和坡面的衔接处设置过渡植被挂设装置；在植被带的下方成排挂设多个蓄水植被块；在坡面上成排的多个蓄水植被块之间的空地上移栽灌木，以及在平台上成排移栽灌木。本发明方法，可快速恢复矿山排土场的植被覆盖并有效保持水土，避免自然灾害的发生。
