Shaft sinking with chemical grout
Problem of sealing porous sandstone encountered in sinking 3000-ft shafts was solved through use of new chemical grout; at 2000 ft level, 100 ft thick, highly porous sandstone with high water inflow was encountered; treatment of sandstone bed to its entire depth was carried out from bottom of shaft through injections into series of holes; AM-9 chemical grout reduced water flow 95%.
