Abstract:

In the process of intelligent mining in coal mine，the advance exploration is very impor⁃

tant. At present，the advance detection of the mining face is carried out on the basis of the stop of the min⁃

ing face，and it cannot be carried out while digging and with digging. During tunneling，real-time advance

Earthquake with Excavation detection system based on online mine seismic monitoring sub-stations. Exca⁃

vation machine vibration collects and transmits to the database of ground server in real time through optical

fiber network. Data processing software obtains current data with excavation from the database. Through

screening，extraction of virtual gun set and migration imaging，the reflected trough wave imaging is carried

out in a certain area in front and side of excavation，and the cutting vibration of integrated excavator is

used as the focal point，and the echo of continuous vibration wave is used to realize the overdue detection

of geological anomalies in front of roadway. Taking transportation roadway of intelligent driving face 1126

（3）in Guqiao Coal Mine as an example，the research on real-time advance detection during excation

technology is carried out. The results show that the position and strike of the fault with a drop greater than

1/2 coal thickness within 100 m can be explored in advance with the excavation earthquake，and the swing

error of the plane position is less than 5 m. The overall accuracy of the detection results is more than 80%，

which forms a support technology for progressive geological transparency in advance detection in front of

the roadway.
