Application of Extension Theory Based on the Analytical Hierarchy Process in the Evaluation of Mine Floor Water Inrush Risk

摘要

In this paper, combining the practice experience and knowledge of the mine floor water prevention field, a matter-element model of mine floor water evaluation Is created based on the extension theory; then the weight of evaluation index Is determined by the AHP; at last the relational degree about the mine floor water inrush risk Is calculated. Through the evaluation of a mine's floor water inrush risk, the conclusion las consistent with the actual, so the practicability of this mine water inrush evaluation method Is verified.
