Abstract: Lithologic analysis and calculation of overlying rock above coal body by taking cantilever beam model, this paper
obtained step distance of roof periodic weighting in mining face, and working resistance scope of hydraulic support, which
provided research methods and data support for roof management in working face.

 Key words: hydraulic support;overlying rock;lithology;support working resistance
