Gob-side entry retaining support system coordinated deformation quantitative design method

The invention discloses a gob-side entry retaining support system coordinated deformation quantitative design method. Firstly, a gob-side entry retaining supporting system is constructed; then a structural mechanics model is established; maximum rotation angles of the basic top rock beams under the four conditions of being limited by the allowable deformation of the anchored coal body of the solidcoal side, the allowable deformation amount of a gob-side filling body, the section service requirement of the gob-side entry retaining roadway and the maximum deformation amount of gangue in the gobare obtained according to the mechanical model; the gob-side entry retaining surrounding rock support is quantitatively designed according to the relative sizes of maximum rotation angles of the basic top rock beams under the four conditions. The method is based on the control of the optimal rotation angles of the lateral basic top rock beams; the quantitative design method for coordinating supporting systems such as gob-
