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 idea of underground coal gasification is connected with the name of Mendeleev 120 years ago. But its practical realization starts during the 30th years of the previous century and continues up to now. There is not any technical or technological problem to perform gasification as a method of processing hard household wastes. In combination with recycling of part of the wastes and utilization of gaseous products of gasification for energy production, this method could be very effective and attractive. If we supp...

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.
