Through the research on the model of the land reclamation in the refuse dumpof Heidaigou open coal mines,it was concerned that ecology was the theoretical basic forthe land reclamation of open coal mines.According to the principle of ecological substitut-ing,the land reclamation can be divided into three stages:water and soil conservation,ecological performance and economic performance.Taking the land reclamation in the re-fuse dump of Heidaigou open coal mines as the practical example,explained the applica-tion of the ecological substituting principle on the land reclamation in the open coal mines.
Through the research on the model of the land reclamation in the refuse dump of Heidaigou open coal mines, it was concerned that ecology was the theoretical basic for the land reclamation of open coal mines. According to the principle of ecological substituting, the land reclamation can be divided into three stages： water and soil conservation, ecological performance and economic performance. Taking the land reclamation in the refuse dump of Heidaigou open coal mines as the practical example, explained the application of the ecological substituting principle on the land reclamation in the open coal mines .
