| Abstract: | According to the problem of the gas content over limit frequently in the upper corner of the U type ventilation in the underground mine and seriously restricted the safety and efficiency of coal production,Through FLUENT simulation,the gas distribution in the mined out area under the condition of fully mechanized mining in Mabao Coal Industry was obtained,and the gas flow field distribution rule in the mined out area was studied.Combined with on site experimental investigation,the guiding gas migration rule in the fully mechanized mined out area and reasonable buried pipe parameters in the mined out area were obtained. |
