The modeling of a multi-motor linear electric drive of a conveyor train is considered. A diagram of the simulation model made in the Simulink program is given. Graphs of the speed and force of the electric drive during the relay transmission of the secondary element are given. The conclusion is formulated that the system fulfills the requirements placed on it.

As part of Sol-Iletsky Mine No. 2, it is planned to erect and set up a health resort center for the treatment of respiratory diseases. This health center will provide medical services in the therapeutic salt chambers on the first horizon (123 meters underground). For this purpose, it is necessary to use the waste horizons of rock salt (chamber workings). For the construction of the health-improving complex for safety reasons in part of underground workings, it is required to arrange a fortification. This article deals with mathematical modeling and selection of the optimal type of support for chamber workings.
