Abstract. The purpose of this work is to establish the disadvantages and advantages of existing foreign and domestic technological developments for the maintenance of workings in iron ore and uranium mines and to determine the most promising ways to increase their reliability.The analysis of the existing technological developments for the maintenance of uranium and iron ore deposits workings made it possible to establish a variety of options for increasing the operational reliability of potentially dangerous areas. Taking into account these results and the peculiarities of the mining and geological conditions of deposits of iron and uranium ores in Ukraine, studies of the stability of mining workings with the application of various technological solutions have been carried out. As a result of the conducted research, it was proposed:

- the use of a rod support based on slag-silicate fast-hardening cartridge mixtures, consisting of a metal rod, a rubber sealing plug and cartridges with fast-hardening mixtures.

- the use of contour (smooth-wall) blasting technology during tunneling, which reduces the dynamic impact of blasting on the rock massif and the formation of additional fracture in its near-contour zone.

It has been established that in difficult mining and geological conditions, protection of workings should be carried out by combined methods. At the same time, both supports affecting the massif in the near-contour zone of the workings and special supports for specific conditions are used. The general scheme of implementation of such methods is given.

Thus, the experience of maintaining workings in difficult mining and geological conditions during underground mining of ore deposits showed the need to continue researching the patterns of deformation and destruction of unstable rocks and creating new technological solutions and supports to solve the problem of maintaining workings and increasing the duration and safety of their operation. The choice of supports for maintenance of workings in specific mining and geological conditions is determined, first of all, by the reliability factor. At the same time, using the existing developments, successfully tested in the underground mining of iron ore, as well as coal and non-mineral raw materials, which allow to increase the reliability and safety of the works, it is necessary to find out the possibility of their application also in the working of uranium mines.

Keywords: uranium and iron ore deposits, stability of workings, technological solutions, fastening of workings, support.
