Abstract:
To perceive and understand the situation of coal mine safety throughout the life cycle of coal mine system is the basis of formulating safety system and the premise of adjusting safety strategy. Only when the safety risk of coal mine system is fully identified can the targeted safety precautions be taken. Based on the mass information of hidden danger record log and coal mine safety function index, combined with the importance of position and function itself, this paper proposes a perception evaluation model that determines hidden danger risk by industry regulations and experts' experience, adopts AHP and entropy weight method to give subjective and objective weights, and makes hierarchical evaluation of coal mine safety situation. The empirical evidence shows that the model can assist safety managers to understand the safety threat of coal mine.
