A structural analysis on the used in processes of open cast mining formula is made and some functional dependences are deduced. This shows the relation between optimal speed on temporary rail ways and the productivity of mounding excavator – single – bucket and with many buckets.A structural analysis on the used in processes of open cast mining formula is made and some functional dependences are deduced.

The influence of temporary rail ways over transporting ability through the mining railway net in open cast mines is researched. A functional relation between optimal speed of temporary ways and the transporting ability is found.

Temporary rail ways in open cast mines influence by the accepted speed for the trains. They have influence on the most important indicator of heavy mining mechanization – the productivity of excavators – stope and mounding. This problem has been always underestimated because a priori has been accepted the dependence between the accepted speed and productivity. This research proves another type of functional dependence – fraction-lineal.

The importance of the influence of temporary rail ways is deduced on the most essential indicator in open cast mining – the productivity of heavy mining mechanization and it is shown how this can be used in practice and through organizing the whole mining process. Also it can be used when corrections through the exploitation of the mine are needed.

The influence of temporary rail ways over transporting ability through the mining railway net in open cast mines is researched. A functional relation between optimal speed of temporary ways and the transporting ability is found.

The optimal numbers of runs of a train in open cast mine is one of the most important technical indicators, on which the work of rail transport in mines is evaluated. A functional dependence between the optimum number of runs of a train and the accepted speed on temporary rail ways in a mine is deduced.

All the specialists in open cast mines which are equipped with technological railway transport know that the transporting process has underlined optional character. This is based on several factors. One of them is the levels intensity of possibility of transportation process to be done without any exceptions. The report is on the principles, on which the levels of intensity can be defined.
