Coal Wall Spalling Mechanism and Grouting Reinforcement Technology of Large Mining Height Working Face

Coal Wall Spalling Mechanism and Grouting Reinforcement Technology of Large Mining Height Working Face

To control the problem of coal wall spalling in large mining height working faces subject to mining, considering the Duanwang Mine 150505 fully mechanized working face, the mechanism of coal wall spalling in working faces was investigated by theoretical analysis, numerical simulation and field exper...
