The Exploitation Technology Evaluation and Selection Based on Grey Situation Decision

The exploitation technology evaluation and selection is a multi-objective planning,production conditions of coal mine have complexity,the information of underground engineering is not complete. In order to avoid the influence of people′s subjective factors and to provide objective evaluation basis to the selection of exploitation technology,this article use the grey situation decision to built multi-objective comprehensive decision matrix,then make decision by calculating the comprehensive effect measure.The appraising result is basically consistent to the fuzzy comprehensive evaluation,grey clustering method and gray Relation Analysis.Comparing with the cultural methods,grey situation decision is more accurate and effective.This method has certain reference value and instruction meaning in the mineral engineering while making decision to a question whose information is not complete.
