摘　　要：河台金矿使用类框架结构采空区新型处理技术之后,近年来在高村与云西矿区产生很多互相独立的采空区,而2002年其中3个相继发生间壁与顶柱倒塌,导致围岩片落,增大了出矿贫化。从理论与实践两方面分析其发生原因以及今后应吸取的教训。Many mutual-independent hollow areas came into being between Gaocun & Yunxi siol since Hetai Gold Mine applied the newly method of homologous framework structure to dispose the hollow areas. But in 2000, three of the hollow areas interstratifications & artificial roofs collapsed conterminous. These caused the brooke shale falling, & increased the ore depletion. This article analyzed reasons & experiences both in theory & practice.
