Abstract
There exists a trend in China that high productivity longwall face which produces 8.0–10.0 million tons of raw coal per annum is widely employed. The stability of the gateroads during the life of longwall mining is the main concern of the success of high-production longwall face. After a gateroad is driven into rock strata, the primary equilibrium state is disturbed and, as a result, the surrounding rocks are unavoidably broken or fractured...
