In recent years, a new field of knowledge has been developed — geoacoustics, which combines a set of acoustic methods designed to solve mining and geophysics problems. Depending on the specific tasks, the frequency range used covers the range from fractions of a hertz to megahertz. Modern geoacoustics is developing in several directions: sound location, acoustic logging, modeling of seismic processes, ultrasonic methods for studying the stress state of rocks...
In resonant measurements, the modulus of longitudinal elasticity E (Young's modulus) is determined for longitudinal vibrations, and the shear modulus G is determined for torsional measurements. For a rock sample in the form of a rod with free ends ...
The sonicolocation method of surveying control and surveying of mine workings is used in the practice of mining enterprises relatively recently. Currently, this method of distance measurement is used in the surveying of dredge ranges, deep open-pit ore dumps, inaccessible underground salt leaching chambers and underground storage of petroleum products, as well as mine shafts and boreholes, conducted by drilling.
