Abstract:
Aiming at the technical problems of shaft lining construction in mining subsidence area,as an example to new auxiliary shaft and return air shaft in Xinzhung mine,a flexble,pressure-unloading,compressible steel fiber concrete composite shaft lining is applied to pivotal horizon in the two shaft walls in mining subsidence area.The optimal mixture proportions of steel fiber concrete and asphalt sliding layer are proposed by test.Structural form and parameter of vertical compressible tie-in are also designed.
