Channel wave seismic exploration technology based on node digital seismograph in underground mine

According to a slow development problem of the mine seismic exploration technology,based on the channel wave seismic exploration technology,a design C onception of the third generation node type seismograph was applied to develop a new type channel wave seismograph with“a node type design,independent excitation,dis tributed acquisition,three channel storage and centralized recovery" .A flexible,unconstrained and free layout of the undergroud mine channel wave seismic observation syst em could be realized.The completed acquisition system with no host computer,no cable,no communication,synchronous acquisition and other advantages and with a high a nd rapid construction could meet the requirements of the channel wave seismic exploration under the overlong and over wide mining face,no connection between the gatew ays as well as the mining block,mining panel and crossed layers condition.
