Analysis About Technology And Methods Of Industrial Disasters’Prevention Planning In Coastal Chemical Industry Zone

Coastal chemical industry zone takes the remarkable economic effect and thespecial geographical position, thus it faces high risk of industrial disaster as well as besubject to the influence of chain disaster resulted from natural calamities, whichseverely affect coastal cities’ social stability and public safet. Therefore theimprovement of the comprehensive disaster prevention plan in coastal chemicalindustry zone is imminent. The author has carried on the related exploration andanalysis of industrial disasters prevention plan in coastal chemical industry zone,which is based on consulting a large number of relevant literature and field research,by using "3s" digital information technology and mathematics model method.This paper constructs the disaster chain of coastal chemical industry zone whichtakes the industrial disaster as the core, as well as put forward the disasters sourcechain scission and mitigation strategy of comprehensive disaster prevention plan incoastal chemical industry zone, on the basis of the clear disasters-inducing factors andcountermeasures of various disasters chains and links. We should practice the insidechain scission and the disaster reduction step by step so as to strive for the disaster inthe bud, or through a series of engineering and non-engineering measures to reducedisaster in time and the transmission of negative energy on the disasters chain.This paper constructs a industrial disasters prevention planning system of coastalchemical industry zone, based on the core of disasters source monitoring and earlywarning, regional risk assessment and emergency evacuation and rescue method. Thesystem has a practice of real-time monitoring for industrial disaster source andautomatic alarming of the abnormal state, combined with the basic geographicinformation and emergency resource information of coastal chemical industry zone,and making evaluation of the source level and scope of the potential disasters. On thebase of which making layout optimization of industrial disaster source and division ofdisaster-prevention function partition of coastal chemical industry zone, in order toguide the campus physical space planning and establishment of emergency evacuationand rescue plan.This paper makes a questionnaire survey, mathematical statistics and softwareanalysis of the on-site investigation of psychological behavior of industrial disasterenterprise personnel in coastal chemical industry zone, concluded with victims of a disaster psychological reaction, behavior patterns and evacuation route choice. On thebase of which the author puts forward the optimization design method for disasterprevention space of coastal chemical industry zone in area, combined with theanalysis of disaster prevention problem about existing evacuation passageway andshelter. Finally, taking Tianjin Nangang Industrial Zone issue planning for an example,the author makes a analysis of optimization design method for disaster preventionspace in the application of fire special planning.
