ARAMIS M/E - Seismic system with DTSS digital transmission of seismic signals


Depending on the extent of the mine, the system is based on seismometers or optionally on low frequency geophones. The system uses intrinsically safe data transmission, centrally supplied from the surface, which enables to transmit 1-, 2- or 3-axial velocity movements (X, Y, Z). The sampling of signals is performed by means of 24-bit Sigma Delta converters, providing high dynamics of conversion and recording.


The processing module of the ARAMIS M/E system works on the basis of the following algorithms:
