【摘要】 针对采空区稳定性评价中评价指标间交互作用机制分析不足的问题,提出了基于RES(Rock Engineering System)-云模型的采空区稳定性二维评价方法。选取了15个采空区稳定性评价指标,基于RES理论,通过建立评价指标交互作用矩阵,分析评价指标间的相互作用,确定了各个评价指标的权重;应用云模型理论计算隶属于不同等级的各指标云模型参数,以指标等级云图的方式进行直观表现,计算样本综合等级隶属度;根据最大综合隶属度原则确定采空区的稳定性等级,引入模糊熵作为第二维评判参量,表征采空区稳定性的复杂程度。最后,将该模型应用于云南某锡矿8个采空区稳定性评价中,验证了该评价模型的可行性。更多还原

【Abstract】 Aiming at solving the problem of insufficient analysis of interaction mechanism between indicators in the stability evaluation for goaf,a two-dimensional goaf stability evaluation method is proposed based on the RES( Rock Engineering System)-Cloud Model. In this paper,15 stability evaluation indicators for goaf are selected.Then the weight of each evaluation indicator is determined by the establishment of interactive matrix of evaluation indicators and the analysis of the interaction between evaluation indicators on the basis of the RES theory. The cloud model parameters for each indicator belonging to different levels are calculated by applying Cloud Model Theory and performed intuitively with index-level cloud diagrams to calculate comprehensive membership degree of levels. According to the principle of maximum comprehensive membership degree,the stability level of goaf is determined,and fuzzy entropy is introduced as the second dimension assessment parameter to characterize the complexity of the stability of goaf. At last,this model is applied to the stability evaluation for 8 goafs in a tin mine in Yunnan,and the feasibility of the evaluation model is verified.更多还原
