Study on lithologic effect of mining-induced failure mechanism of coal seam floor
In order to obtain the mining failure characteristics of coal seam floor with different lithology, the Mohr circle solution of the influence of different internal friction angles on the strength of rock mass is established, and the correlation formula between the ratio of the maximum floor failure d...
