科学采矿是人类从自然界获得煤炭资源的更高级阶段,关系到人类社会与生态环境的安全发展、和谐发展、健康可持续发展。为了实现科学采矿由定性描述到定量表达的升华,构建了由5个一级指标、33个二级指标和64个三级指标组成的科学采矿评价体系数学模型。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,实现了评价指标的无量纲化处理;采用改进的专家主观赋权法实现了权重的动态化。用科学采矿指数作为模型计算的惟一结果,并用之表达被评价煤矿的科学采矿状况。
Scientized mining is the objective requirements of human beings for coal mining,and the advanced stage for human obtaining coal resources from the nature.The scientized mining has been related to the human social and ecological environment safe and harmonious development,and also healthy and sustainable development.Based on the connotation of scientized mining,guarantee measures and objective analysis of the mining conditions,confirmed the scientific evaluation system which composed of by 5 first-class indexes,33 second-class indexes and 64 third-class indexes.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 to achieve the evaluation index of the dimensionless processing.Combined with industry characteristics,respectively,in the process of weight determination and quantification,give full play to the role of evaluation expert,and by optimizing subjective weighting of experts participation together,realizes the target weights of evaluation system in dynamic.Using scientized mining coefficient(ScMC) to quantify expression the scientized mining level of the evaluated mine.
