This invention relates to the field of mine ecological restoration technology, and discloses a method and
system for mine ecological restoration. The
restoration method includes selecting an area with residual heat from underground
coal fires on a mine slope where residual
coal has spontaneously combusted as a restoration zone; reinforcing and stabilizing the slope of the restoration zone; laying a
sludge substrate with a
moisture content of 60%-80% on the stabilized slope surface, and using the residual heat from the underground
coal fires for in-situ biological
drying until the
volume reduction reaches a preset threshold of 40%-60%; subsequently, covering the dried
sludge substrate with a soil substrate layer and a soil microbial substrate layer to construct a composite growth matrix; and finally, maintaining
vegetation on the slope. This invention cleverly combines the residual heat from abandoned mines with urban
sludge treatment, achieving the harmlessness, reduction, and
resource utilization of sludge, while simultaneously solving the problems of excessively high soil temperatures and difficulty in
plant survival in mining areas, achieving the goal of ecological restoration through
waste treatment and synergistic efficiency.
