The article states the objectives of geotechnical monitoring in an open cast mine and discusses the main measurement methods. Distributed ledger technology (DLT) is recommended for monitoring and sharing data on the condition of the mine slopes between private and public organizations. Private DLT implementation is chosen because confidential corporate data is shared. A conceptual model for communication among the Mining Company, the responsible institutions and regulatory authorities has been suggested. It has been established that there is a possibility of leakage of personal data according to the GDPR.

In the present study, the peculiarities of local heat treatment with a concentrated light energy flow of non-metallic materials are traced. Mathematical dependences are presented for determining the surface density of the absorbed power - W(r), the thermal power - Po, and other characteristics in case of local thermal impact on the surface of non-metallic materials with a concentrated light energy flow.

The publication examines the peculiarities of alloying a matrix of water-dispersed iron powders of the type ASC 100.29, AHC 100.29 and ABC 100.30. The possible ways of alloying in powder metallurgy are presented. The influence of the main alloying elements - copper, nickel, phosphorus, molybdenum, etc. was traced. on the technological process in the production of powder metallurgical details. A special place is given to the alloying elements intensifying the process of coagulation of the pores in the matrix during sintering - copper and phosphorus. Graphical dependences for the influence of copper on the dimensional changes of the iron matrix at different sintering temperatures are presented.
