Description

Technical Field

[0001] This utility model relates to the field of earthquake monitoring technology, and more specifically to a prefabricated source monitoring well device. Background Technology

[0002] Microseismic monitoring and 3D microseismic exploration are two geophysical exploration technologies developed to meet the needs of resource exploration. Microseismic monitoring involves deploying nodal seismometers to establish a source monitoring network, collecting active source motion signals from the site for location analysis, recording the seismic source location, timing of occurrence, and magnitude calculation. 3D microseismic imaging is performed by collecting natural source motion signals from the site, establishing a 3D seismic wave velocity model of the subsurface medium, and conducting goaf detection and structural exploration. These technologies can serve mineral resource monitoring, safety production monitoring, and evaluation.

[0003] During the establishment of the seismic source monitoring network, dozens of nodal seismographs need to be buried in the field to form the network. If the nodal seismographs are buried directly underground, they are easily submerged in the field environment, making them susceptible to damage or theft, which is detrimental to the protection of the instruments and equipment. Once the equipment is damaged or lost, it will also affect the acquisition, interpretation, and analysis of data, thereby affecting the quality of the data results and impacting the work.
