%X 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.
