Reducing of mining cost by means of adopting structural parameters of super stope
采用超级采场结构参数降低采矿成本的探讨
Based on the analysis of the evolution of the structural parameters of non - pillar sublevel caving of mines both in and outside china , it is pointed out that increasing continuously the sublevel height is not suitable for application in china because of the limitation of various factors while increasing the access space is the main way to reduce the amount of developing work , reduce the mining cost and increase the one - time caved ore amount so as to raise the mining strength and the labour production rate
分析了国内外矿山无底柱分段崩落法结构参数演变过程后指出，继续增大分段高度由于诸多因素的限制，在我国并不适宜推广应用，而增大进路间距却是减少采准工程量、降低采矿成本、增大一次崩矿量、提高采矿强度和劳动生产率的主要途径。
