摘要
为了实现科学采矿由定性描述到定量表达的转化,构建了基于主观动态权重的数学模型。该模型由7个一级指标、37个二级指标和64个三级指标构成评价体系,采用专家定参法、标准取值法、开关函数法、分段函数法、定性取值法等手段,可实现评价指标的无量纲化处理;同时,采用改进的主观专家赋权法实现指标权重的动态化。该评价模型可适用于不同条件的矿井,并用科学采矿指数(ScMC)作为表达科学采矿水平的惟一综合指标。
Based on the connotation of scientized mining,guarantee measures and objective analysis of the mining conditions,confirmed the scientific evaluation system which composed of 7 first-class indexes,37 second-class indexes and 64 third-class indexes.Combined with industry characteristics,respectively,in the process of weight determination and quantification,gave full play to the role of evaluation expert,and by optimizing subjective weighting of experts participation together,realized the target weights of evaluation system in dynamic.By the use of method with experts-input-parameter,the standard value method,switching function method,sub-function method,qualitative value method,and other means are employed to achieve the evaluation index of dimensionless processing.Using scientized mining coefficient（ScMC） to quantify the expression of scientized mining level of the evaluated mine can be realized.
