Results of the survey of the operation of drainage systems in Estonian oil shale mines

Abstract
The Estonian oil shale deposit is characterized by large water inflows reaching 6000-8000 m3 / hour in spring floods (e.g. at the Käva II mine in April 1955). The geodetic height of water rise is small: 20-40 m - for the main drainage and 3- 4.5 m - for the sectional pumping.
