Abstract

In order to reduce the fuzziness and uncertainty in rock burst intensity evaluation caused by incomplete information, an evaluation method for rock burst intensity was proposed based on grey target decision-making theory. Firstly, evaluation index system was constructed, and grey system theory was introduced to confirm the weighted coefficient of each index. Then the multi-attribute grey target theory was introduced to construct multi-dimensional evaluation model for rock burst intensity. Space projector distance was used to construct distribution sets of the comprehensive bull's eye distance under different intensity levels. Finally, rock burst intensity grade was determined by measuring the off-target distance.

RESULTS show that the assessment results by the proposed method are in line with the actual situation, and that compared to the Russenes criteria and rough set theory, the proposed method can reduce the fuzziness of decison caused by incomplete information and give more explicit intensity degree of the test sample. © 2019 China Safety Science Journal
