24 Channels Engineering Seismograph for Underground Exploration
Engineering seismograph, also known as shallow seismograph, generally refers to the exploration depth of nearly hundreds of meters within the scope of seismic exploration instruments. Engineering seismometer can be used for refraction exploration, PS logging in hole, cross hole earthquake, for engineering construction services. It can also be used as a data acquisition system for multichannel transient surface wave exploration. The whole system is small, lightweight, easy to transport, anywhere using a small 12V DC battery can work. Engineering seismograph is widely used in mineral, hydrogeology, engineering geology and other fields.
The seismograph uses hammer, electric spark or explosion as the source to stimulate the observation and record the travel time of seismic waves, to detect the buried depth, shape and distribution law of different elastic stratum interface, to solve the problem of engineering and resources geophysical exploration, exploration depth from several meters to hundreds of meters, but also through time delay recording, to obtain deeper buried depth data.
