Abstract

Abstract:

In order to prevent the occurrence of fire accidents caused by external factors in coal mines, achieve efficient and rapid response after the risk is out of control, and minimize casualties and property losses, the Daliuta coal mine of Shendong Coal Group was used as an example. The key external factors causing fire accidents in large and super-large coal mines were analyzed, and pre-disaster prevention and control measures were summarized. In addition, emergency response technologies were explored. The results show that long-distance tape machine friction ignition, overheating of high-voltage cables and equipment, and spontaneous combustion of auxiliary transportation vehicles are key external factors causing fires in large coal enterprises. Emergency response technologies such as airflow short circuits, local backflow, new air door control, fire zone closure, and compressed air self-rescue can be adopted to deal with fire accidents caused by external factors in coal mines. Fire accidents caused by external factors in coal mines feature common occurrences, serious losses, and difficult responses. Therefore, a comprehensive management technology combining pre-disaster prevention and emergency response is needed to ensure the safety of mine production.

Key words: coal mine, fire accidents caused by external factors, factors causing fires, prevention and control measures, emergency response
