In this paper, the test site is the working surface hollowing area of Luling Coal Mine 8, coal seam III 811, and the distributed fiber temperature measurement is carried out. Distributed temperature measuring fibers and beam tubes are arranged in the inlet and return wind lanes of the work surface for continuous monitoring. After analyzing the data such as measuring temperature and gas concentration, the remote monitoring technology of the temperature field in the mining area is expanded. Finally, combined with the self-ignition characteristics of the Luling coal seam and the classification criteria of the “three zones” in the mining area, the range of the self-ignition hazard area of the III 811 mining area is accurately determined. This paper provides theoretical and technical support for the development of targeted fire prevention measures and remote monitoring.
