The invention relates to a method of leading
silt in the Yellow River to fill reclamation
coal mining
subsidence land, and belongs to the technical field of mine environment protection. The method comprises confirming distributing characteristics of time and space and the amount of required
silt of the
coal mining
subsidence land to be filled through methods of remote-sensing images, mining
subsidence prediction and field investigation, selecting
silt-taking points and silt-taking equipment according to the river regime of the Yellow River, a
riffle area distributing condition and the positions of subsidence regions, conveying silt through pipelines composed of a main
pipe and
branch pipes, setting up a relaying
booster pump station, guaranteeing long-distance conveying of the silt, taking reclamation steps such as direct surface soil stripping, stripping after drainage and direct filling against regions to be filled, then conveying silt to fill the regions to be filled, timely draining in the filling process to accelerate silt
sediment, covering filled silt with
peripheral stripping soil or covering the filled silt with soil dressing, and forming filling reclamation land with
high productivity.
