Abstract：It is an important measurement in decreasing mining-caused land destruction by building super-high bench dumping-site. Foundation loading，stability analysis，mud-rock-flow and water control are key factors in decision making. By the new study，a great scale dumping-site in Qijiagou of Changba，which is 400 m high has been built. Meanwhile，mechanism of foundation loading，technology of determining the limit height of dumping-site，corresponding stability analysis，and a new method of controlling mud-rock flow by controlling small and tiny grains have been developed. The first sluiceway of dumping-site has been built successfully in our country. Afterward，these techniques have been developed widely in Miaoergou dumping-site of Nanfen. Better effects have been obtained. Therefore，this technique can be used widely for reference in other mines.
