Abstract
The deepening of a mine shaft is a difficult and dangerous operation. Moreover, it requires the continuous operation of the shaft during the process of deepening. Because of this, it is necessary to leave the plug on the shaft bottom or install an artificial shaft bottom. The main task of an artificial shaft bottom is to provide safety from falling objects for the employees working on the shaft bottom. Many solutions for shaft safety platforms have been used in Polish mines over the years. A new construction of the artificial shaft bottom consists of using layers of highly durable net. It allows a reduction in the construction weight as well as the installation time. This article presents a new construction of an artificial shaft bottom and the simulations and calculations that confirm the possibility of its application to mine shafts during their deepening.
