Abstract

The main problem today is the fight against annual natural fires. Peat fires cause irreparable environmental and material damage, as a result of which the fertile horizon is completely destroyed, poisonous gases are released, residential buildings and warehouses are destroyed, and habitats for animals and plants disappear. A peat fire is difficult to extinguish, since peat is a powerful water absorber and most of the water sources are located at a considerable distance from the source of ignition, special equipment fails in places where it burns out. The aim of the work is to substantiate moistening by means of canal locking to restore a hydrological regime and to combat the occurrence of fire in the existing drained systems of the Moscow and Ryazan regions. The main locking indicators for 53 years were obtained for two options for moistening in comparison with standard dehumidification. The articles of the water balance were calculated and studied. The optimal variant of moistening the peat bog was chosen, which creates fire-prevention conditions and conditions for the development of agricultural conditions. According to the selected option, water supply is about half of the total drainage flow, there is no need to attract additional water resources.
