Unbalanced rock mass vibration generator and its bench testing

This work presents an unbalanced borehole vibration source with the pneumatic actuator to affect the rock mass bottomhole zone in the seismic frequency range. The modulus-type source consists of the vibration generator with automatic step regulation of static moment, clamping node and built-in pneum...

Description
Summary:This work presents an unbalanced borehole vibration source with the pneumatic actuator to affect the rock mass bottomhole zone in the seismic frequency range. The modulus-type source consists of the vibration generator with automatic step regulation of static moment, clamping node and built-in pneumatic device to transfer equipment in uncased boreholes. There are test results on the source prototype, amplitude and frequency characteristics and spectral content of the source signal.
