Numerical Analysis on Drainage Parameters in a High Drainage Roadway
Year: 2015
Type: article
Abstract: The numerical tests of the optimized drainage parameters in a high drainage roadway were conducted with different inlet air velocities, drainage ratios and integrity lengths. The results show that the upper corner's gas concentration decreases gradually with the inlet air velocity and drainage ratio increasing, while there have not obvious change with the Different Integrity Lengthss. Considering from the gas control and gas drainage, the reasonable inlet air velocity is 1-1.25m/s and the right drainage ratio is about 0.3.
