Wantai Microseismic Technology currently supports three-dimensional monitoring of the entire mine, both above and underground

Wantai microseismic technology is to deploy high-sensitivity microseismic sensors around the monitoring area to comprehensively, real-time, three-dimensional and high-precision monitor microseismic activities caused by rock mass changes, and locate the temporal and spatial characteristics of these microcracks, including the location of the event, the size of energy Seismic moment, focal mechanism and other information, so as to provide information on coal mine Rock burst, mine water disaster Conduct dynamic monitoring, evaluation, and early warning on the stability of surrounding rock and prevention and control of cross-border mining.

Through mine earthquake+microseismic monitoring, the micro phenomena such as rock mass micro fracture signal energy and fracture density are captured, and then the dynamic monitoring and evaluation of coal mine Rock burst, mine water disaster, surrounding rock stability and cross-border mining prevention and control are carried out, which has the advantages of regional monitoring and early warning.

Software system

The system modules include engineering configuration software, real-time acquisition software, microseismic processing software, and microseismic 3D visualization software.

Engineering configuration software is a software that facilitates users in establishing engineering and project management. Its main function is to help users import the configuration parameters of the monitoring area's acquisition instrument and the recorded raw waveform data into the computer for automatic or in-depth manual processing and analysis.

Microseismic processing software

Quickly process the microseismic data collected from the field, filter the microseismic data, perform waveform transformation, pick up the first arrival of its P and S waves, and then calculate the positioning information and source information of the microseismic event through positioning calculation.
