采空区危险性的RES-可拓联系云评价模型研究

RES-Extension Connection Cloud Evaluation Model for Goaf Risk

为真实反映指标的分布特征与交互关系,提高采空区危险性评价的准确性。提出一种基于RES-可拓联系云的采空区评价模型。研究结果表明:RES能直观反映采空区危险性评价的指标与指标、指标与采空区系統的交互关系,并且能甄别出采空区危险性评价的关键指标与非关键指标;可拓联系云能吸取物元可拓理论与传统云模型的优势,同时能较好地弥补两种理论的缺陷,更贴合实际。最后,通过与来知确度法评价结果对比,验证了该模型的可行性与先进性。

In order to truly reflect the distribution characteristics and interaction of indicators,improve the accuracy of goaf risk assessment,a goaf evaluation model based on RES-ex tension connection cloud is proposed.The research results show that RES can directly reflect the interaction between the indicators and indicators,the indicators and the goaf system of the goaf risk evaluation,and can identify screen out the key indicators and non-key indicators of the goaf risk evaluation.Extension-linked cloud energy can absorb the advantages of matter-element extension theory and traditional cloud models,and at the same time can better make up for the shortcomings of the two theories,and is more in line with reality.Finally,the feasibility and advancedness of the model were verified by comparison with the evaluation results of the unknown certainty method.
