Abstract

Abstract:

In order to create a method to evaluate the intelligent level of the open pit vehicle safety guarantee system in the coal mine, so that builders and planners can understand and master the intelligent construction level of open pit coal mine vehicle safety guarantee system, the intelligent safety evaluation system of open pit coal mine vehicle safety guarantee system was proposed and established. The integrated automation(IA), management informatization(MI), engineering digitization(ED) effect and the synergistic relationship among the three were analyzed, and the intelligent evaluation model was studied and created. The intelligent evaluation formula of the vehicle safety guarantee system of the open-pit coal mine was refined and summarized, and the corresponding deduction was made. The research results show that the evaluation model can fully quantify the abstract concept in the intelligent construction, and intuitively show the wisdom degree of the open-pit coal mine vehicle safety guarantee system, which can reflect the overall intelligent construction level of a mine.

Key words: open pit coal mine, vehicle safety guarantee system, wisdom, evaluation system, vehicular traffic, evaluating indicator
