Stability Analysis of Gob Roof and Rock Movement Prediction

Stability Analysis of Gob Roof and Rock Movement Prediction

In order to analyze the stability of the gob roof, the RMR rock mass classification was used for rock quality evaluation to calculate the rock condition and the collapse possibility of the gob roof was proved by the results of the 3D FEM numerical analysis, thus took the-140m level as an example, th...

description In order to analyze the stability of the gob roof, the RMR rock mass classification was used for rock quality evaluation to calculate the rock condition and the collapse possibility of the gob roof was proved by the results of the 3D FEM numerical analysis, thus took the-140m level as an example, the monitoring scheme for the gob roof movement was designed, then the time series prediction was analyzed for rock movement. Based on the results of predicting data, the rock movement value of the gob roof was increasing gradually, supporting scheme should be formulated to control the rock movement value.
