This paper expounds the conditions of the occurrence of the flammable dust explosion, probes into the explosion mechanism, the explosion parameter, the factors of influencing the explosion and protection method, and reveals the basic features of the dust explosion.

This paper introduces the theory of flammable dust fire and explosion accident, and describes prevention measures of dust explosion accidents and their fire fighting measures.

In this article, the development and existing condi tions of classificat ion for combustible dust areas is introduced in both China national and foreign relevant standards.

The results of experiments and analysis revealed the basic characteristics of interactions between shock waves and the combustible dust layer.

The author gives the discussion on the explosive protection technology applied on lead acid storage battery used in combustible dust environment and the examination and testing to this sort of product, based on the inherent characteristics of lead acid storage battery.
