摘　　要：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。大间距无底柱采矿工艺更加适合我国当前的生产力发展水平,便于应用和推广。For a long time,the small structure parameter that was 10m × 10m was abopted by non-pillar mine in our country, which restricted the advantage of non-pillar to develop. 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. It is the first structure parameter of non-pillar in our country.
