| Abstract: | Introduced features and the source of gas emission on fully-mechanized top coal caving face.In this paper,some factors were discussed,such as gas content of exploitation bed,mining intensity of working face,the gas emission of adjacent seams and atmospheric pressure.It also proposed some gas control measures,such as upper corner gas control,ventilation mode transformation,the layout of roof gas drainage roadway,boreholes construction for roof gas drainage,and the application of even pressure technology on f... |
