Essay

In the dissertation the way of increase of metal support bearing ability of capital workings in conditions of aggressive mine waters is proved. The laws of change of speed of corrosion from scale presence, salinity of mine waters, stresses arising in a support are established. The structures of throwconcrete mixes with use of ashes of ablation are developed as replacement of a part of cement and the analysis of protective action of the given coverings in relation to metal is carried out. The established dependences have lain in a basis of throwconcrete covering thickness definition technique depending on conditions of operation at use of a way of increase of metal support bearing ability in conditions of aggressive mine waters
