Abstract
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.
