充填采矿法充填挡墙合理结构参数研究及应用

Research and application of reasonable structural parameters for filling retaining wall in cut-and-fill mining method

为保证充填采矿法的充填效果、采场围岩及充填体稳定性,对空区充填挡墙的结构参数进行了理论研究并在现场应用,结果表明所设计的充填挡墙结构参数合理适用,降低了矿山充填成本,并对矿山下一步的充填工艺提出了建议。

Theoretical research was made of the structural parameters For filling retaining wall is the mined-out area to ensure the filling effect of cut-and-fill mining method, surrounding rocks in stope and filling stability. The structural parameters have been applied on the site. The research results showed that the designed structural parameters are reasonable and appropriate with less mining costs. Besides, some suggestions on the subsequent filling process are presented.
