Foundations on mine spoil material
(OP)
I am designing a silo and a storage tank on a mine spoil. The total thickness of the mine spoil is about 55m and about 10 years old.the unfactored load of the silo is about 70kPa and that of the storange tank is about 80kPa.
Can anybody help me with the design of the foundation especially the settlement.

You really need to properly characterize the soil modulus.
p.s., where's the ground water table? My reply doesn't account for primary consolidation, which needs to be looked at also, but may ultimatly not be a factor.

Some corners can be cut on the required surcharge height, since the "bulb of pressure' from the tank foundation is likely smaller than that of the surcharge.

Ten years may not be enough for the fill to have reached a stable moisture content. Preloading with a surcharge can be effective if the soil is saturated or will never see an increase in moisture content, but it can forget its stress history if it absorbs more water.
Your project sound like a challenging one.

No matter what, it will be important to properly characterize the geotechnical properties of the mine spoil.
