It is important to reduce the span of the hard roof to avoid its impact load on supports. However, at longwall top coal caving face, the periodical weight of roof is a main factor that crushes the top coal, which is beneficial to the top coal recovery. How to use the roof pressure safely is of crucial importance in top coal caving. Based on field monitoring, theoretical analysis of strata movement, the numerical model of compound structure of hard roof stepped cantilever and the top coal cantilever beam is built, and the parameters of the model are also determined. The elasto-plastic finite element method is used to analyze the effect of hard coal fracture under the abutment pressure of hard roof, and the cracking coefficient is defined according to the stress state of the element.
