Regarding the underground environment containing explosive gases and dust, the risk of explosion in the working environment is caused by ignition sources formed by non electrical explosion-proof equipment such as hot surfaces, mechanical sparks, and thermal reactions. This article proposes a method for suppressing ignition sources of non electric explosion-proof equipment based on D-S evidence theory and multi-sensor data fusion. It uses multiple sensors to collect information about the possible ignition sources that may form in the entire non-electrical system.It analyzes and evaluates the data characteristics formed by the working environment and different ignition sources to suppress the generation of non electric equipment ignition sources in underground environments containing explosive substances. Warning and initiating appropriate protective measures for potential ignition sources.It can ensure the safety of underground working conditions.
