Support Technology of “Bolt-Steel Mesh-Anchor-Shotcrete”+Steel Pipe Concrete Liner in Mine Roadway
DING Jiagui
Abstract： An end section of a north wing railway cross—cut in East Kouzi Mine was high in depth and pressure. After a heading operation,a “bolt—liner—grouting” support was applied and the deformation failure was serious.With a same support mode applied to the roadway repair,the deformation failure was occurred again. Therefore a study and application on the support of the“bolt—steel mesh—anchor— shotcrete” + steel pipe concrete liner was conducted and a successful application was obtained. After the application,there was no obvious deformation occurred,the deformation failure of the mine road way was effectively controlled and the technical and economic benefit was obvious.
