浅议液压支架工作阻力计算

Discussion on the Working Resistance Calculation of Hydraulic Support

采用悬臂梁模型,通过对煤体上覆岩层岩性分析和计算,得出回采工作面顶板周期来压步距及工作面液压支架工作阻力范围,为回采工作面顶板管理提供了研究方法和数据支持。

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.
