Embodiment Construction
[0037] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0038] Such as Figure 1-4 As shown, the mine earthquake source location method based on the underground communication optical cable of the coal mine includes the following steps:
[0039] Step 1: Use the underground communication optical cable 2 as the carrier, connect one end of the communication optical cable 2 to the laser 1 on the ground, connect the other end of the communication optical cable 2 to the wavelength division multiplexer 3, and connect one end of the wavelength division multiplexer 3 Connected with a polarization measuring instrument 4;
[0040] Step 2: By controlling the laser 1 to send an optical signal with a polarization state to the communication optical cable 2, the polarimeter 4 at the other end of the communication opti...
