Study on Determination of Working Resistance of Supports in Large Height and Fully Mechanized Caving Mining Face Under Thin Direct Roof

To propose the mechanical relationship between the support and the surrounding rock of the large-scale high-level fully mechanized top coal caving mining face, and to derive the calculation formula of the working resistance of the hydraulic support, the 13# coal seam mining of Xiegou Coal Mine is us...
