Hydraulic support is an important support means for roof subsidence and collapse. Studying the working resistance of main support in the mining process of working face has an important theoretical and technical guiding role for roof stability. Taking 14301 working face in Shendong mining area as an example, the influence of working resistance on the support work is studied. Through analysis, it is preliminarily concluded that the linear relationship between initial support force and final resistance is strong and the formula is $\mathbf{y}=\mathbf{Ax}^{2}+\mathbf{Bx}+\mathbf{C}$. The data distribution is relatively centralized and $\mathbf{R}^{2}$ is about 1. The supporting effect can be improved by adjusting the size of both.
