Study on Gas Flow Law in Goaf of Huangling No.1 Mine Fully-Mechanized Face

Tian Xuan Hao, Meng Liu

Abstract

The gas concentration field in goaf of Huangling No.1 Mine 304 fully-mechanized face was simulated numerically by FLUENT software with high fracture drilling or not. The results of numerical simulation were confirmed by fixed sampling method of immersed tube in goaf. Thus, the law of gas concentration field was gained, which provides the important basis for gas control of working face.
