武平紫金公司充填挡墙受力分析与厚度计算

武平紫金矿业有限公司井下空区多而乱,为了消除空区的安全威胁且更好的回收地下矿石资源,采用全尾砂胶结充填系统充填新旧空区。针对武平紫金公司-115m中段81-3空区,对所设置的1#、2#挡墙的受力特点进行分析和计算,并结合该空区情况,计算出所需挡墙厚度值,为矿山后续其他空区的充填挡墙设计提供参考借鉴。

Mechanical Analysis and Thickness Calculation of Backfilled Retaining Wall in Zij in Mining Company of Wuping

There were many chaotic underground mined-out areas in Zij in mining company of Wuping.In order to eliminate security threats and recover underground mineral resource much better,cemented filling system of unclassified tailing is used to backfill the mined-out areas.For 81-3 mined-out area at -115 m level,mechanical characteristics of 1# and 2# retaining walls are analyzed and calculated.Considering the mined-out area condition,required thickness of retaining walls is obtained,which provides a reference for backfilled retaining wall design in other mined-out areas.
