Abstract


A comprehensive evaluation of coal mine safety situation usually involves three aspects , that the establishment of coal mine safety evaluation index system , the rational allocation of the index weight and safety evaluation method of choice . View of the coal mine production system complexity , risk factors variability and concealment , the establishment of coal mine safety evaluation index system should follow certain principles , in order that the index system can be fully and effectively reflect the safety of coal properties . Reasonable indicators of the index system weight distribution to more truly reflect the degree of importance of the indicators in the comprehensive evaluation of coal mine safety is placed in front of many scholars to be an important issue for further study . The thesis is based on trying to achieve a breakthrough in the index weights assigned . There is no doubt that the problems can be resolved smoothly directly determines the coal mine safety comprehensive evaluation of the results of scientific nature and effectiveness . The theoretical framework of the evaluation of coal mine safety in detail, the theoretical framework mainly includes three aspects , establish principles and procedures of Coal Mine Safety Evaluation Index System Combination Weighting Approach theoretical research and local variable weight theoretical research ; this theoretical framework as a guide , the underlying data is collected , the paper then applied based on least squares objective and subjective combination Weighting Method local variable weight theory for coal mine safety evaluation index system of constant weight vector and different coal mine their specific local variable weight vector ; Finally, get constant weight vector and local variable weight vector , coal mine safety evaluation often right the integrated value of the local variable weight comprehensive value were detailed comparison and analysis , concluded combination of empowerment and local variable weight indicators to optimize weight distribution vector, to improve the overall results of the evaluation of the reliability of this conclusion.
