Abstract

Shaft equipment plays an important role in the process of exploitation loading. The main load is concentrated on the basic buntons, which are horizontal metal H-beams and they are fixed into the shaft support by both ends. In shafts with skip hoisting of useful minerals the destruction of upper flanges of buntons from multiple frontal impacts of rock pieces weighing 150-200 kg, the impact of mine water drip and corrosion is observed. As a result, it is necessary to change shaft equipment during working life of a mine shaft. In order to reduce the magnitude of push loading from falling pieces of rock and ore spillage, effects of corrosion and reduction of labor costs for repair and reconstruction works the construction of bunton for stiff metal shaft equipment was developed, in which the horizontal flange of H-beam is protected by a firmly fixed metallic bracket. The bracket reduces the kinetic energy of the falling pieces of ore or rock spillage in the shaft with skip hoisting; as a result, the bunton working life is prolonged. The construction can be used for shaft equipment of vertical shafts of coal and ore mines.
