The Unascertained Measurement Model of Safety Risk Evaluation in Mine Construction Sites

In order to establish a safety risk prevention mechanism and reduce the losses caused by accidents in a mine construction project, this paper proposes a risk evaluation model for a mine construction project based on unascertained measure. The unascertained measure include civilized construction site, management of machinery, equipment and materials, occupation health protection, the sub-package management and so on of one level evaluation indices of six, inspection system of safety risk, safety awareness education, prevention and control of occupation disease, such as 33 two level evaluation indices. We calculate the weights of the first index by using the information entropy and the AHP theory for second index. A case study is conducted using an empirical project demonstrates that the model proposed is of practical significance and economic value, and provides a reference to risk management for a mine construction project.
