Substantiating operational parameters of load- haul-dumpers in the context of irregular-shaped underground mine workings

Objective of the paper is to substantiate scientifically parameters
and design of energy-efficient transportation and operational schedules for
ore masses transfer by means of new-generation load-haul-dumpers
(LHDs) adapted to real mining environment at different development
stages. Features concerning formation of cargo traffics and components of
mining as well as tunneling systems in the context of uranium deposits
mining have been studied. Mathematical model to identify operational
indices of load-haul-dumpers has been developed. Layout features of the
spaced pin-connected frame construction have been used to develop
mathematical models of disturbed motion. Potential sources to improve the
efficiency of load-haul-dumpers in the context of mining intensification
have been analyzed.
