Embodiment Construction
[0018] The roadway (or tunnel) excavation seismic advanced detection device with the roadheader as the seismic source of the present invention, its preferred specific implementation mode is:
[0019] It includes a seismograph, a seismic source signal receiving sensor arranged on the arm of the roadheader, and a seismic wave receiving geophone array arranged on the roadway wall. The seismic source signal receiving sensor and the seismic wave receiving geophone array are respectively connected to the seismograph. The source of vibration is the cutting head of the roadheader.
[0020] The seismic source signal receiving sensor is a three-component sensor, and the seismic wave receiving detector is a three-component detector.
[0021] The seismograph is an underground explosion-proof seismic signal data acquisition instrument capable of continuously acquiring massive seismic data.
[0022] The above-mentioned tunnelheading machine of the present invention as the seismic source re...
