Abstract
The standard methods of laboratory determination of the elasticity modulus of rocks under uniaxial compression are analyzed and their advantages and shortcomings are discussed. A test method and internal standard which enable physically correct determination of the static elastic properties of rocks upon change in their condition (temperature, moisture) are developed. Testing includes multiple loading of the specimen within the range of low reversible strains. The test is preceded by compulsory pre-compaction (2 loading cycles). Conditions of the reversibility and linearity of deformations are checked in subsequent cycles. The examples of determining the elasticity moduli of the siltstones of enclosing rocks from the «Botuobinskaya» diamond deposit as a function of their temperature and moisture are presented.
