Research on safety hazard prediction of open-pit coal mine based on improved grey model
WANG Feng
Abstract：In order to prevent production safety accidents in open-pit coal mines and improve the accuracy of hidden danger prediction,an improved prediction model is proposed and developed.Taking Changxu Open-pit Coal Mine as the research object,based on the mine safety risk monitoring and management information platform,the traditional grey GM(1,1)model and two improved prediction models(BX grey model and BX grey Markov model)are carefully evaluated and compared.The results show that the BX grey Markov model is the best among the three models.The model shows a high degree of accuracy,helps to formulate more accurate risk management and hidden danger prevention and control strategies,and effectively prevent the occurrence of safety production accidents.
