Abstract:

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.

Key words: Rocked-gold mine, mining in hollow areas, homologous framework structre, hollow area stability
