It was proposed a method for the prediction of the occurrence of fourteen day resonances of gravitational tides in the Earth's crust. The data of registration of parameters of tidal gravitational factors including fluctuations of the barycenter in Earth-Moon system in different geophysical fields was presented for the first time. It was given the estimation of the amount of changes in the stress-strain state of the geological environment under the resonances influence. It was substantiated possible directions of using energy of the resonances of gravitational tides in the Earth's crust in oil and gas fields, the earthquake prediction, security of large man-made structures (hydroelectric dams), and the development of theories of single deformation killer waves.
