FIELD: mining.
SUBSTANCE: invention refers to coal and ore mining, particularly to methods of construction of vertical shafts various in depths and designation. The technical result is achieved like follows: sinking of the shaft is performed with passes and with drilling and blasting operations, with loading broken rock and with construction of temporary roof bolting. Upon sinking the shaft to a complete depth there is upwards constructed a constant reinforced roof; also space between an installed reinforced ring and the roof bolting is filled with concrete mortar.
EFFECT: simplification of process and acceleration of rate of sinking and shaft rigging.
