Water Leakage Control in An Iron Ore Shaft in Hebei

Abstract:

An iron ore shaft in Hebei was constructed by drilling. After removal of steel casing in the shaft, water leaked around the shaft wall. Several methods, such as filling the shaft with mud, slip casting on the bottom of shaft, lateral drilling and slip casting behind the wall of the shaft and laying an water leakage wall, were take to stop the leakage. Finally the water was blocked.
