Numerical Simulation of the Prevention of Gas Accumulation at the Upper Corner by High - located Gas Drainage Roadways
Abstract：The gas accumulation in upper comer is a problem that must be solved in high gas fully mechanized caving face. According to the practical situation in 8103 working face of Tashan coal mine, the method of setting a high - located gas drainage roadway to pre- vent gas accumulation at the upper comer is proposed in this paper. Based on the theory of Computational Fluid Dynamics （CFD） , the mathematical - physical model is built to calculate the flow laws of air and gas in fully mechanized caving face and goal. The feasibility and reliability of the method are analyzed, which is tested by the practical project.
