Method for determining load of coal seam overlying strata structure support under shallow-buried coal-pillar-crossing concentrated load

The invention relates to the technical field of coal seam mining, in particular to a coal seam overlying strata structure support load determining method under shallow-buried coal-pillar-crossing concentrated loads. Analyzing a bearing structure of a sub-key layer II under the action of the concentrated bias load of the section coal pillar, and constructing a rock stratum structure mechanical model; analyzing disturbance bearing structures on the two sides of the section coal pillar through an analog simulation experiment; determining the load characteristics of an interlayer rock fracture bearing structure based on the disturbance bearing structures on the two sides of the section coal pillar; the supporting resistance of the structural support is determined by combining the load characteristics of disturbance bearing structures on the two sides of the section coal pillar and an interlayer rock stratum fracture bearing structure; the supporting resistance of the structural support is the load of the structur
