Using ridge soil to pile up a ridge band on the subsoil exposed after stripping the surface soil from the coal storage yard. After spraying compound microbial inoculum on the ridge band, the ridge can be covered with black plastic film with air permeability, then open the plastic film next year, and plant crops on the ridges. In that reclamation method, the decomposition and transformation of the coal powder in the surface soil can be accelerated, the soil nutrient can be activate, the status and permeability of the soil nutrients can be improved, and the reclamation and reasonable utilization of the waste land of a coal storage yard can be realized. It provides an effective solution for the safe and efficient reclamation of abandoned coal storage yard in China.
