Abstract
The authors investigate modes and parameters of mining operations with a view to create conditions for transmission of geotechnologically produced kinetic energy of rocks to electric generators. The features of application of energy harvesting equipment in underground mining of hard minerals are discussed. The low-frequency energy trap designed to entrap elastic energy of rock mass oscillations operates in a wide range of amplitudes and frequencies of rock mass vibration, and is composed of three nonlinear oscillators having preset mass and elastic characteristics.
