- 8. a kind of method of shallow buried coal seam tunnel fire prevention Anti-air-leakage according to claim 7, which is characterized in that the S2 In, specific step is as follows for trace gas detection:S201: being arranged in the environmental signal in the trace gas detection unit acquisition goaf of the detection unit of coal seam goaf, when When collecting search gas, acquisition signal is sent to analysis controlling unit, user indicates according to analysis controlling unit, determines It leaks out place；S202: the inflammable gas detection unit that the detection unit in the tunnel to be measured of coal seam is arranged in acquires easy combustion gas in tunnel to be measured Body content, and acquisition inflammable gas content signal is sent to analysis controlling unit, and be shown to user；S203: user controls analysis controlling unit and opens gas extraction unit, and gas extraction unit extracts in tunnel to be measured Gas carries out detection confirmation for user.
- 9. a kind of method of shallow buried coal seam tunnel fire prevention Anti-air-leakage according to claim 7, which is characterized in that the S4 In, specific step is as follows for environment in monitoring tunnel:S401: temperature in temperature detecting unit real-time detection tunnel, and temperature signal is sent to analysis controlling unit；S402: when temperature collection is higher than the temperature threshold of setting, analysis controlling unit control fire prevention isolation part is closed；S403: analysis controlling unit controls gas extraction unit and opens, and extracts gas in fire protection space, to cool down, extract easily Fire extinction using gas.
