Background In the mining process, the heavy metal pollution of the soil is one of the most outstanding environmental hazards, and the soil has concealment, long-term property and irreversibility, so that not only can the physicochemical property of the soil be destroyed and the soil be degraded, but also peripheral water bodies can be polluted by surface runoff and rain water leaching, and vegetation is directly poisoned or human health is threatened by food chain enrichment, and double hazards are formed for ecology and human survival. In the repair technology of heavy metal contaminated soil, chemical repair is the most widely applied means, and the core of the technology is to add an improver into the soil, reduce the bioavailability of heavy metals through adsorption, oxidation reduction, antagonism or precipitation, and the technology has the advantages of in-situ operation, simple and convenient flow, high construction efficiency and controllable cost, and is very suitable for the actual requirements of large-scale mine repair. However, at present, most mining areas still use the traditional chemical restoration mode of directly spraying or drilling injection modifier, the migration of the modifier completely relies on natural leaching and gravity permeation, the modifier is easy to quickly run off along a preferential flow path in heterogeneous soil media due to lack of an effective artificial guiding and controlled releasing mechanism, the modifier is difficult to fully contact and react with soil particles, the passivation efficiency of heavy metals is low, and the restoration effect is extremely unstable, the problem is particularly prominent in mine slope restoration, and the current spray-seeding mode is difficult to cause soil loss and seed rooting due to the fact that the slope is mostly a bare steep slope and the attachment of foreign soil is difficult, meanwhile, the modifier solution is mainly lost in the downward slope direction due to the influence of gravity, the upward slope direction is difficult to be effectively restored, the restoration range is limited, the overall restoration effect is uneven, and the long-acting ecological restoration target is difficult to realize.
