Description	On the bases of experimental and analytical investigations methodical procedure was worked out for calculation of loads on supports of horizontal mine workings which were driven in zone of winning operations influence. It was established that the most unfavourable geomechanical situation is in period of finishing of panel extraction when abutment pressure value reaches its maximum. Laboratory simulation data, which were received on models consisted of optical active material, helped to established abutment pressure geometry, space orientation of load peak and depth of winning operations influence at different levels of horizontal sections, it allows to estimate geomechanical situation for mine workings with different space orientation. As a result of analysis of abutment pressure geometry and numerical parameters analytical dependences were worked out for redundant pressure value estimations for mine workings placed in zone of winning operation influence.
