摘要: 针对高寒高海拔地区急倾斜薄矿体特殊的开采技术条件,基于几种常规开采急倾斜薄矿体的采矿方法,综合考虑影响采矿方法优选的11个因素指标,运用模糊数学层次分析法计算出相应采矿方法的权重矩阵,同时利用线性函数法及二元对比排序法确定各指标隶属度矩阵,建立综合评价指标模型。得出中深孔嗣后废石充填机械化采矿法最优,进而解决了青海高原矿山人工劳动强度大的难题。

Abstract: According to the special mining conditions of sharply-inclined and thin ore-body in the alpine high-altitude area, based on several conventional mining methods for sharply inclined and thin ore-body, and taking the 11 factor indicators that impact mining method into consideration, the weight matrix of corresponding mining method is calculated out with the use of analytic hierarchy process.Meanwhile the linear functions and the binary comparison sorting method are adopted to determine the index membership matrix, building a comprehensive evaluation index model.It is concluded that medium-hole mechanized mining method with subsequent waste rock filling is superior, and the heavy labor problem in Qinghai Plateau is solved as well.
