The article presents the way of conducting a forecast of leverages of underground mining run by longwall fronts in three deposits of hard coal on the area. The forecasted values of subsidences, inclinations and curvatures of mining area were calculated by the Budryk- Knothe theory with the use of typical values of its parameters, namely, a coefficient of subsidence of floor rocks equal to 0.8 and tangent of scope angle of main leverages amounting to 2.0. The forecasts of indicatorsпїЅ values of area deformation we...
