Abstract: The vibration energy of the roadheader during it excavates coal and rock is treated as the source in seismic while heading in coal mines, which avoids the hazards and hindering normal heading operation caused by the explosive source.Therefore, it has the advantage of carrying out underground seismic exploration while coal mine is in normal heading operation.However, due to the low energy of coal-rock excavated by the roadheader, the SNR（signal-to-noise ratio） of the pulse-like source obtained by... More
