The questions of the influence of technological parameters (water level, weather), which depend on the rate of drying of products, in the development of the peat field “Svyatinskoye”, and, more precisely, in the field drying of peat crumb obtained by milling the deposit, are considered. For the experimental maps of the production site the indicators of seasonal studies are given. For this purpose, the moisture content of the dried layer, indicators of groundwater level fluctuations and the volume of moisture, which was absorbed from the underlying deposit and rainfall, moistening the dried peat layer, were determined. On four maps with an open drainage network, weather conditions as well as groundwater level fluctuations in the map channels were monitored during the season. The complexity of laying of slot drainage and its influence on the water-air regime of the uppermost deposit during the ground water level variation during the season were analyzed. It is shown that slot drainage together with open channels has favorable effect on production site drainage. It has been established that ground waters under the action of gravitational forces, i.e. at the difference of pressures in the peat deposit and drains, seep into the cavity and then under the slope are discharged into the collecting network of open channels and are removed outside the drained production site. It is recommended to use the results of seasonal studies and analysis of moisture movement processes to develop and substantiate measures for improving the water-air regime of the peat deposit with the development of an intensive method of drainage as well as for maintaining the necessary conditions.
