Features of the operating conditions of emergency rescue cages of lifting installations in vertical shafts of mines

Purpose. Establish the peculiarities of operation of emergency rescue cages of mine shaft hoisting units to extend their functions in the conditions of intensification of mining production and determine the directions of their modification. The methods. The study of the peculiarities of operation of hoisting vessels in real conditions of the mine environment was considered as an interacting transport and technological system «cage ‒ conductors» using classical methods of analysis, generalization, comparison and modeling. Findings. Comprehensive studies of the operation of rescue cages in the specific conditions of mines in Western Donbas have established a bank of typical, atypical and extreme factors that negatively affect the performance and technical condition of the elements system of the«cage –conductors». It has been experimentally proven that in order to increase the adaptive capacity of the rescue cage, it is necessary to additionally determine the little-studied indicators of the peculiarities of the impact of the mine environment, as well as the dynamic loads arising from the deviation of the vessel from the vertical position during movement.In order to expand the effective use of rescue cages as a mobile service complex, it is necessary to equip rescue cages with modern information and measuring equipment for monitoring the technical condition of the interacting elements of thesystem «cage –conductors»and to formulate and approve at the appropriate levels the concept of creating a special service for the maintenance of the lifting complex. The originality. For the first time, the peculiarities of the influence of deformations of the profile of conductors of shaft reinforcement in the planes Ox and Oy on the performance of the elements of the dynamic system «rescue cage – conductors» under conditions of uncertainty were established. Practical implementation. The expediency of modifying the emergency rescue cages of mine shaft lifting units in order to use them as a technical means for servicing the lifting complex during operation has been proved
