Technical Field

[0001] The utility model relates to the technical field related to underground coal mines, in particular to an underground coal mine disaster risk safety monitoring and early warning device. Background Art

[0002] Gas explosions are very likely to occur in coal mines, so when working underground, the risk of disasters in coal mines will be monitored and warned in order to remind workers in advance and reduce personal injuries caused by accidents.

[0003] The existing publication number CN111691922B discloses a coal mine underground disaster risk safety monitoring and early warning device based on wireless communication. It sets multiple groups of first monitoring mechanisms and multiple groups of second monitoring mechanisms. The monitoring detection surfaces of the monitoring components of the first monitoring mechanisms are all facing and facing the tunnel wall of the coal mine tunnel. In this way, the airflow emitted from the tunnel wall can be monitored in detail to ensure the reliability of monitoring. Each group of the second monitoring mechanisms of the present invention includes at least three monitoring components, and the respective monitoring detection surfaces of the three monitoring components are all facing the direction away from the tunnel wall.
