Abstract: In allusion to the grim actuality of safety situation of coal mine in China and the problems existed in construction of domestic information system of coal mine safety management, the paper proposed the establishment of support system platform of intrinsic safety of coal mine with open system architecture, which is accorded with management status of domestic coal mine and can reflect modern informatization theories and methods of coal mine management. The platform is based on theory of intrinsic safety, and takes risk pre-control as the core and the intrinsic safety of human, machine, ring and management as main line. The platform realizes identification and investigation of major dangerous source, predictive analysis and classification evaluation, which minimizes the risk of accidents. The platform uses measures of visualization training, position responsibilities, institution and measure management combined with related equipments to improve safety knowledge and skills of the staff, make them have a good safety awareness, and ensure the effective implementation of various safety measures, so as to achieve intrinsically safe management of coal mine.
