Grabar E. Research of territory undermining impact on the water losses in anthropogenic regions and choice of optimum technologies for the loss replenishment

Thesis deals with the ecological situation analysis of territories of undermining closed work in connection with the water-supply problems. The state of the channel "Severskyy Donets - Donbass" is described and total deformations of the earth surface along the route of channel. The technology of channel pipelines correction without water drain by means of two mine pneumatic fastenings set in the third-point is suggested. The formation model of benches in drift bed which can be applied in internal force amount prognostication caused by bench curvature in pipelines is worked up. The interaction of cast-iron pipes flush joint with the sideview of bench sideview is analyzed. Polyethylene tubes stress on the bench is analyzed and advisability of polyethylene tubes application is analyzed. Recommendations on loss replenishment of drinking water by means of mine water stoping and different ways of loss reduction of drinking water in heating systems are worked up. The dependency relation of scale depositing speed from temperature and product of hardness on circulating water alkalinity is defined. Rationality of water treatment in filters charged by carboxyl cation is grounded.
