Collecting water samples for laboratory analysis from hard-to-reach surface areas such as post-industrial reservoirs (for example, tailings depositories) or overgrown lakes and ponds poses several difficulties, and it is potentially dangerous for the persons carrying out such activity. This can be improved by the use of unmanned aerial vehicles (UAVs) while ensuring an adequate level of safety and full compliance with the requirements of PN-ISO standards. This article presents the possibility of using the BSP in the option of autonomous (automatic) operation, allowing for the collection of water samples intended for physico-chemical tests, from hard-to-reach surface reservoirs, following the provisions of the relevant PN-ISO standards.

The synergy of fatigue, corrosion and abrasive wear processes in operation of mining round link chains

Vol. 66, no. 1

29--42

The mutual influence of fatigue processes, abrasive wear and corrosion of chain links on the functional properties of mining round link chains has been presented in this paper. Selected results of experimental investigations in the field of synergic impact of these destructive processes on the operational durability of mining chains have also been presented. The emphasis was given to the necessity of a comprehensive consideration of destructive processes that occur in various conditions of use of round link chains applied in mining machines.
