| Abstract: | Based on the roof collapse law of the stoping face in a goaf,the gas travel rule and flow equation in the goaf were analyzed. The gas concentration variation rule and isoconcentration field along depth of the goaf were acquired. Combing with the existing gas drainage method of the goaf,it played a certain positive role for gas drainage in the stoping face of the goaf in a coal mine. |
