Current Status and Issues of the Safety Protection System for the Production Systems Engineering of Burning Explosives

doi:10.12382/bgxb.2024.0931

Abstract

Abstract:

The air shock waves, fragments, thermal radiation, explosion effects and propagation patterns of explosive system, as well as the allowable levels that personnel, equipment and other burning explosives in the explosive system can withstand are analyzed, and the typical engineering protective measures for explosive manufacturing are discussed. These measures include sealed anti-explosion structures, personnel shelters, protective barriers, and safety distances. Based on engineering practice experience, with the aim of saving land resources and further balancing the effectiveness and economic rationality of engineering protection, it is proposed that the following issues need to be continuously studied and improved: the quantitative evaluation method for combustion and explosion effects in different scenarios, the quantitative evaluation method for the degree of destruction caused by accidents, and the risk-acceptable criteria and quantitative evaluation and optimization method for the effectiveness of engineering protection measures.

Key words: burning explosive, safety protection system, explosive system detonation effect, allowable endurance of explosive body, engineering protective measures
