Problem of the infusion of a fluid in an elastic deformable medium

The problem of the infusion of a fluid in an elastic coal seam via a hole drilled from the daylight surface is solved. Analytical expressions that make it possible to investigate the effect of the stress—strain state, physicomechanical and collecting properties of the coal, and the rate of injection on the process of fluid infusion under prescribed conditions, are obtained.Donetsk.
