Research of 6206 Fully Mechanized Caving Face Goaf Gas Flow Field and Concentration Distribution Rule of Wangzhuang Coal Mine

ZHAO Dong1,ZHANG Xue-bo2,DENG Quan-wei2(1.Wangzhuang Coal Mine of Lu'an Environmental Energy Development Co.,Ltd.,Changzhi 046031,China;2.School of Safety Science and Engineering of Henan Polytechnic University,Jiaozuo 454003,China)  
Application of a numerical simulation on goaf gas flow field and concertration distribution at 6206 fully mechanized face mining by using of computational fluid dynamics(CFD) software Fluent at different sections,and gain migration rule of goaf flow field and gas under the conditions of "J" type ventilation.The results showed that the use of "J" type ventilation system can reduce goaf concentration of air leakage upper corner,it plays an important role of effective solution to the accumulation of gas upper corner.
