1) great-interval stopes
大型大间距
1.
Study of strucural parameters of great-interval stopes adopted in Meishan iron ore mine;
梅山铁矿采用大型大间距采场结构参数的探讨
2) large space
大间距
1.
By comparing with the small structure parameter, the large space parameter is super in some aspects,such as improving mining intention,and reducing preparatory work,and reducing mining cost,which is the current productivity of our country and is easy for application.
我国无底柱矿山长期以来,基本上采用10m×10m(分段高度×进路间距)左右的小结构参数,限制了无底柱采矿法优越性的发挥,大间距结构参数较小结构参数而言,对增大开采强度,减少采准工程量,降低采矿成本等均具有明显的效果。
2.
