Rigidity effect of the mine geophone mounting on its frequency response

Purpose. To determine the rigidity effect of changes in mine geophones mounting on frequency response recorded seismoacoustic signals. Methodology. Operational calculus and analysis are used. Findings. The dependences characteristics under coupling conditions with rock studied. A possibility is shown qualitative change signal when changing installation case a geophone; moreover, increase can result both decrease amplitude components fixed range. calculations performed for parameters characteristic current use most common rocks. Electrodynamic velocimeter piezoelectric accelerometer were considered separately. Originality. Frequency by geophone be caused at between rock. ratio to natural serve as an indicator possible effect. Numerical values this proposed. Practical value. Critical obtained data, taking into account measurement time. need their initial periodic control parameter further operation.
