摘　　要：以国内某大型露天煤矿薄煤层开采为例,提出3种技术可行开采工艺方案,在对备选方案进行技术经济比较的基础上,建立灰色数学模型,对备选方案进行优化选择,最终确定该矿薄煤层开采应采用露天采矿机-前装机-卡车开采工艺,利用露天采、运设备生产能力的计算公式计算所需设备数量。Taking thin coal seam mining for example in the large open-pit coal mine, the article presents three kinds of feasible mining technology. On the basis of comparing the technology economy of the schemes, the mines establishes the gray math model,carries out optimization choice on the schemes, and finally determines thin coal seam mining adopting open-pit mining machine-front loader-truck mining technology. The mine uses the calculating formula of mining and transportation equipment production capacity to calculate equipment number.
