ON ISSUE OF THE CALCULATION OF INCOMPLETE WELLS

The article was dedicated to the issues on calculation of incomplete wells that have a different construction and are used in different hydrogeological conditions. By using hydraulic methods, the simple, exact and universal calculation formulas have been proposed for calculating bore and mine types of incomplete wells situated in pressure and pressureless layers work with only flat and semi-spherical bottom, at the same time, flat bottom and filter, also semi-spherical bottom and filter. Formulas proposed according to six schemes allow predicting the decline of the level in the well and water-carrying layer, determining the debit of the well and hydrogeological parameters. Results from the proposed formulas have been compared with the results from formulas given by different authors to the same scheme in the case of concrete examples and their exactness has been evaluated.
