Abstract: Intelligent coal mine is the only way for the development of coal industry in the new era,which is the core technical support for the transformation of production mode of coal industry in the future. In view of the existence of coal production risk,the coal mine safety guarantee system under the intelligent condition should adapt to the intelli gent level of coal mine. This paper systematically discusses the definition,connota-tion and technical characteristics of the intelligent safety system of coal mine,and points out that the intelligent safety system of coal mine’ s core lies in accurate geological sensing,comprehensive data platform,real-time risk assessment and intelligent disaster disposal, forming a digital,one-stop and intelligent closed-loop of coal mine risk identification,early warning and processing.This paper introduces the structure of intelligent safety system of coal mine at the perception level,risk level,equip ment level and management level,and puts forward four technical connotations:the accurate full dimension perception of coal mine,the accurate risk identification and early warning of coal mine,technology intensive coal mine safety man agement concept and intelligent equipment system with function of self-inspection and self-repair. First of all,at the technical level,the key technical system based on the transparent geological support technology,with the coal mine big data sharing platform as the carrier,and with the coal mine major risk assessment and early warning technology as the core,which needs to be solved,is described,and the solution path is preliminarily given. Then,it discusses the system architecture and core technology of the system software platform. Its main purpose is to realize the ‘integration’ of sys tem data,the ‘visualization’ of element display,the ‘intelligence’ of risk assessment and the ‘platform’ of operation software. Finally,the intelligent safety management and control platform system for intelligent safety of coal mine is de veloped,which realizes the comprehensive visual operation platform of coal mine,big data analysis platform of coal mine,intelligent risk assessment of coal mine,multi-system coordinated control and mobile terminal display function, and explores a feasible technical path for building a complete intelligent safety system of coal mine.
