Abstract:
In order to explore the influence of multi-disaster chains on emergency rescue system, this paper analyzes many kinds of disasters such as rock burst, coal and gas outburst, roof accident, flood, fire and coal dust explosion.And it also summarizes the types of chain disasters, and analyzes the causes of chain disasters.The analysis shows that the overlap of disaster occurrence area and the inducement between disasters are the basis of the occurrence of chain disasters, which makes chain coupling occur.This paper summarizes the existing emergency rescue system and the rescue mode for single disaster, and finds that the singularity of the rescue mode can not meet the post-rescue of multi-disaster chains, and does not form a comprehensive multi-disaster rescue system.This paper expounds the influence of chain disasters on the change of the primary and secondary relationship of disaster prevention and control, and studies the influence on the whole rescue system.The results show that chain-disaster is a kind of complex chain coupling process which is based on multi-scale, multi-space-time and multi-induction, and has great influence on the disaster prevention and rescue system of coal mine.
