Abstract In this paper，an elastic supporting beam model for powered support groups based on supporting characteristics of powered support is proposed，the stiffness matrix of powered support groups with the method of discrete single span beam is derived，the formulas of deflection of the rock beam and of supporting resistance of hydraulic powered support groups are obtained，the equation of supporting stress field of powered support is established，and a corresponding simplified calculation method is presented. The supporting stress field of powered support in different surrounding strata conditions and structure patterns of powered support are studied and a specific example is described. Finally，the specific conditions of application and direction of development of the theory are put forward.

Key words： mining engineering powered support elastic bearing stress field ultra long coal mining face
