Model of moisture movement in field dressing of peat in the large spreading

Article preview

The possibility of using the model equilibrium disturbed peat system to assess the effectiveness of gravitational drainage of the peat material hill without evaporation from the surface, depending on the height of the critical thickness, flow rate and the amount of moisture in the layer after deposition.

Mechanisation of extraction of peat from undrained deposit

Article preview

In comparison with traditional methods of extraction using the offered equipment and developed technological schemes for industrial production of a peat will allows to avoid actions on drainage of developed fields; to reduce expenses for preparation and operation of a peat deposit; to prolong a season of mining activities, and in some cases to provide an opportunity of all-the-year-round operation of a deposit.
