Determination of Stresses in Rock Bodies by the Velocity of Propagation of Elastic Waves.

Results of the application of the seismic method to the determination of stresses in rock bodies are described. A method of measurement of absolute stresses by the velocity of propagation of elastic waves of the sound frequency range is presented. In accordance with the data of natural-size investigations for conditions of an iron ore deposit, calibration dependences of V equals f( sigma ) are constructed. The results obtained indicate fairly high reliabilty and precision of the proposed method of stress determination.
