The review of the national and international experience shows that the traditional methods of rock salt leaching during construction of underground storage facilities for gas and liquid fuel fall short of the actual level of mining technology and equipment. Many research institutions strive for improving methods and means of in-situ leaching of rock salt using bore holes drilled from ground surface. An innovative method is proposed for construction of underground structures using acoustic vibrations. A creative element of the proposition is hydrodynamic rotary radiator generating acoustic vibrations. In this case, at the phase interface (liquid–rock salt), specific phenomena arise and accelerate rock salt dissolution. The design and operation principle of the hydrodynamic rotary radiator are described. The design provides adjustment of acoustic vibration frequency, which enables generation of resonance oscillations. The lab-scale investigations into intensification of rock salt leaching with the developed hydrodynamic rotary radiator are reported. It is found that the salt dissolution rate depends on the acoustic pressure amplitude at the phase interface. The investigations show that high-power acoustic vibrations within a frequency band of 500–3000 Hz intensifies the process of salt dissolution by 1.5 times and more. The investigations prove efficiency of acoustic vibrations in construction of underground storage facilities in rock salt.
