Research in the Impact of Dynamic Loads for the Development of Pentice Designs when Sinking Skip Shafts
T.F. Gorbachev Kuzbass State Technical University, 650000, 28 street Vesennyaya, Kemerovo, Russian Federation
In order to protect workers engaged in shaft sinking works artificial protective equipment (buntons) with the support element from powerful I-beams or truss structures are used. They have to withstand enormous push loading, be strong, simple in design, have less labor input during construction and dismantling. Under shaft sinking in case of skip operational winding performance, a protective bunton can be exposed to the rock mass flow in the event of an emergency full skip run. To substantiate the variables and develop the design of pentices when sinking an active hoisting shaft, the skip falls time dependence on the changes in its fall height, taking into account the velocity and the air stream direction in the shaft, was established using mathematical modeling. LLC “SibGorComplexEngineering” together with the Department of Construction of Underground Structures and Mines of T.F. Gorbachev Kuzbass State Technical University have developed several new designs variants of protective buntons for vertical shafts sinking in case of operational winding performance. It is a Z-shaped structure of the offset in height, parallel to each other of upper and lower protective buntons, bushed with sloped reflective metal sheets and it is interconnected by a vertical division wall.
