2.3 Experiment in the mine
The experiment has been performed in one of the mining units in the underground mine.
A route for hauling the ore is presented in green on the map in Fig. 2. A specific feature of this
part of the mine is a serious change of elevation (several dozen meters) that significantly influence the operation of the machine (more load going up, playing with breaking system going
down). Due to extremely harsh conditions, signals acquired on mining machines have to be carefully inspected, validated and preprocessed before they are subjected to proper analysis [12, 13].
