[0002] In the process of coal mining, on-demand exploration technology is a cutting-edge technology applied to mine geological exploration. It can detect the geological conditions ahead in real time during the tunneling process, providing a strong guarantee for the safe production of the mine.

[0003] Existing technologies for geological exploration during tunneling mainly include two types: seismic exploration during tunneling and electrical resistivity tomography (EDT). Seismic exploration during tunneling utilizes the vibration signals generated by the tunneling machine cutting coal walls or breaking rocks as a seismic source. Data is collected by sensors and then transmitted to computer equipment for processing and imaging, enabling real-time detection of geological conditions ahead of the tunnel. However, during long-term observation, it has been found that existing vibration sensors are usually installed by drilling holes in the tunnel sidewall and then sealing them with concrete.
