Abstract
The article describes the procedure of estimating spatial distribution of pressure in a producing formation under mining by the ground surface geodesy survey data. The numerical experiments show that one-valued solvability of the inverse problem requires the ground surface motion to be measured both in vertical and in horizontal directions.
