摘　　要：矿产资源绿色开发为当今矿业关注的重点和难点,胶结充填采矿法已成为目前广泛推广应用的技术之一,但缺少充填系统低碳等级评价体系。为准确评价矿山充填系统的低碳性,引入未确知测度模型,选取了10个影响指标,构建了单指标未确知测度函数,确定了基于测度函数的各指标的组合权重。通过将4座矿山指标实测数据代入测度函数中,计算了单指标测度矩阵,结合权重向量,计算了多指标综合测度,确定了山东某矿山全尾砂膏体充填系统的低碳等级为Ⅱ级,新疆、内蒙古和四川3座矿山的粗尾砂膏体充填系统低碳等级均为Ⅲ级。在此基础上,利用建立的低碳性评价模型对湖南某铅锌矿全尾砂膏体充填系统指标参数进行了优化并推广应用。结果表明,通过优化充填胶凝材料灰砂比、增大输送管径、加强易磨损区弯管耐磨度及定期翻转管道等措施,可以将低碳充填系统评分由68.23增至81.62,评分增长程度为19.62%,评价等级由Ⅲ级提升至Ⅱ级。研究成果对低碳充填系统研发和建设具有良好的借鉴意义。The green development of mineral resources is the focus and difficulty of the current mining industry.The cemented filling mining method has become one of the widely used technologies,but it lacks a low-carbon grade evaluation system for the filling system.In order to accurately evaluate the low-carbon performance of mine filling system,the unascertained measure model was introduced,10 influence indexes were selected,the single index unascertained measure function was constructed,and the combined weight of each index based on the measure function was determined.By bringing the measured data of four mines into the measurement function,the single index measurement matrix was calculated.Combined with the weight vector,the multi-index comprehensive measurement was calculated.The low-carbon level of the whole tailings paste filling system of a mine in Shandong was determined to be grade Ⅱ,and the low-carbon level of the coarse tailings paste filling system of three mines in Xinjiang,Inner Mongolia and Sichuan were all at grade Ⅲ.On this basis,the index parameters of the whole tailings paste filling system of a lead-zinc mine in Hunan were optimized and popularized by using the established low-carbon evaluation model.The results show that by optimizing the cement-sand ratio of the filling cementitious material,increasing the diameter of the conveying pipe,strengthening the wear resistance of the bends in the wear-prone area,and regularly flipping the pipe,the low-carbon filling system score can be increased from 68.23 to 81.62,the degree of growth is 19.62%,and the evaluation grade is increased from grade Ⅲ to grade Ⅱ.The research results have good reference significance for the development and construction of low-carbon filling system.
