The technology of monitoring and early warning and intelligent prevention and control for mine exogenous fire

There are some problems in the prevention and control of mine exogenous fire,such as single monitoring means, low accuracy of early warning,lack of auxiliary decision-making for emergency response,and inability to realize in-situ disposal of fires,and the level of intelligence needs to be improved urgently. To realize the integrated solution of accurate early warning and intelligent coordinated control of exogenous fire, this study comprehensively describes the research progress of mine exogenous fire monitoring and early warning and intelligent prevention and control from five aspects: information perception,data integration,intelligent early warning,auxiliary decision-making, and coordinated control. Specifically, in terms of information perception,advanced monitoring methods are adopted,and high-precision detection equipment is developed,and accurate early warning indicators for exogenous fires are optimized to achieve dynamic perception of fire information throughout the process. In terms of data integration,it is recommended to unify the standards for data acquisition,transmission,storage and access interface standards,and standardize the access of various types of data. In terms of intelligent early warning, the key parameter identification method of intelligent early warning and early warning strategy are proposed. In terms of auxiliary decision-making, a one-stop solution including spatio-temporal information processing, spatio-temporal map construction, spatio-temporal analysis and intelligent decision-making is constructed. In terms of coordinated control,an intelligent coordinated control system including broadcasting system,safe escape system,ventilation control system and fire extinguishing system is established.
