A Numerical Study of Stress Distribution and Fracture Development above a Protective Coal Seam in Longwall Mining
Coal and gas outbursts are serious safety concerns in the Chinese coal industry. Mining of the upper or lower protective coal seams has been widely used to minimize this problem. This paper presents new findings from longwall mining-induced fractures, stress distribution changes in roof strata, stra...
