DETERMINATION OF SOIL DENSITY AT COMPRESSION TESTS Russian patent published in 2015 - IPC G01N9/00 

FIELD: mining.

SUBSTANCE: claimed process comprises the determination of the soil specimen main bulk. Measurements are executed at, at least, two pressure stages (in odometer). Note here that at pressure increases from the step to another one, the soil deformation increment is measured up to deformation stabilization. Note here that, additionally, the extra specimen of made. Then, extra identical specimen is dried to a constant mass. Then, it is dried to said constant mass. Now, dried soil specimen weight and volume are measured to calculate the dried soil initial density. Then, the specimen density is defined for all pressure stages. Note also that drying can be made up to 105°C to settling of the constant mass. Soil density for all pressures can be defined by he formula , where ρ_d,₀ is dry soil density, h₀ is the specimen initial height, Δh is the absolute specimen deformation.

EFFECT: expanded applications.
