Optimization Research on Roof Control Scheme of Large Angle Fully Mechanized Mining Face in Coal Mine Underground
In order to solve the problems of easy fragmentation of the roof and coal wall fragmentation in the 6306 fully mechanized mining face roadway,a control scheme of"grouting reinforcement+brown rope reinforcement"is proposed.The effectiveness of this scheme is simulated and verified using FLAC simulation analysis software.The technical parameters of the reinforcement work scheme are determined,and the application of grouting reinforcement and brown rope reinforcement in the underground is discussed.According to practical applications,it is shown that this control scheme can completely solve the problem of coal wall fragmentation underground.
