Embodiment Construction
[0020] The method of long-distance diversion of Yellow River silt filling and reclamation coal mining subsidence proposed by the present invention is described in detail in conjunction with the accompanying drawings and embodiments as follows:
[0021] The method proposed by the present invention for long-distance diversion of Yellow River silt filling to reclaim coal mining subsidence land, such as figure 1 As shown, it is characterized in that the filling of the coal mining subsidence is restored to cultivated land, and the long distance is that the distance of transporting the filling is greater than 30km; it includes the following steps:
[0022] (1) Predict the spatial distribution and sand demand of coal mining subsidence to be filled at different time points: through remote sensing image interpretation, mining subsidence prediction, and on-site investigation methods, the spatial distribution and total subsidence of coal mining subsidence at different time points are dete...
