Wind erosion and runoff erosion alternatively take place under the action of wind force and runoff force in copper mine and tailings storehouse with high dam and big storehouse，and with very loose texture and very low resistance to erosion because lack of cement property for tailings sand parts. Soil erosion mudulus reaches 80 OOOt/kmZ.a in the slope of dam meanly，wind erosion mudulus reaches 30 000-40 OOOt/km’in the inside of storehouse.Surface erosion and gully erosion take place easily if the protective works were not carried out well.which will result in harmfullness. To conserve the stabilitydam is the key for secure storaged ahean·lsTsuch as dam structure，of tailingstailings dam and the integrity of slope and top of dam for every sub storehouse. Attention should be paid to every measure for erosionresistance， storehouse protection of dam anddam slopeand Utilization top of suberdam of tailing from the start of storehouse construction.coverin soil on dam protection beneficial measure to control erosion thoroughly around storehouse，and to turn harmfullness popularized and applied in the same mine regions on a big scale.benefity. measures should be popularized and applied in the same mine regions on a big scale.
