Study on Parameters of Support for Control of Roof Fall and Rib Spalling in Large Fully Mechanized Top Coal Caving End Face

He, Fu Lian / Wang, Xiao Ming / Zhang, De Quan / He, Shang Sen

Key factors affecting the control of roof fall and rib spalling are identified relying on the statistics for characteristics of roof fall and rib spalling distribution, and the regression analysis of the relationships of roof fall and rib spalling to support parameters by measuring actual ground pressures. The effect of support in controlling roof fall and rib spalling is analyzed by setting up a caving arch mechanical model of cataclastic coal and rock mass on fully mechanized caving face, and the key parameters of support are also determined using numerical simulation.
