Research on Mechanism and Control Technology of Rib Spalling in Soft Coal Seam of Deep Coal Mine
In order to solve the difficult problem of coal wall spalling of soft seam in deep mining, the occurrence mechanism of coal wall spalling in deep mining is studied based on the limit equilibrium theory of D-P criterion. Through the analysis of the formula of plastic zone, it can be concluded that th...
