Study on Goaf gas drainage parameter optimization
In order to obtain a good result of gas drainage in gob roof, combined with SiHe coal mine drainage method, as well as the drainage problems, for high towards long-hole effect of the unbalanced nature of drainage, making theoretical analysis with Darcys law at the same time use of CFD software to simulate gob air flow pattern and gas migration way in order to determine the best long-hole process parameters such as the optimum interval between drilling fields and best position of boreholes, etc, to provide a theoretical basis for designing high level gad drainage hole in goaf.
