摘要: 分析研究了无底柱分段崩落法矿石隔离层下放矿理论可行性,并利用SLS系统对其进行了模拟实验,模拟结果表明:矿石隔离层下放矿是可行的,得出结论:为减小隔离层厚度允许隔离层表面一沟一平交替出现,并不破坏隔离层的作用;若使各分段放矿后隔离层一直保持平面下移,但需要增大隔离层厚度。

Abstract: The theoretical feasibility of ore-drawing under ore isolating layer in pillarless sublevel caving was studied and the simulation experiments were carried out using SLS system. The results show that the method is feasible. To reduce the isolating layer's thickness, the alternating convex-concave of the isolating surface is allowed, which will not damage its function. To keep a planar downward movement of the isolating layer between sublevels, the insolating layer's thickness should be increased.
