Study on roof deflection distribution of ultra-long working faces based on matrix displacement method
To investigate the effects of roof conditions, sidewall conditions, and support conditions on roof deflection variations in ultra-long working faces, and to apply beam model theory to hydraulic support design, this study is based on the ultra-long working face 132202 of Xiaobaodang No.2 Mine. A two-...
