Experiences with application of roadway air-ducts made of artificial fabric used at 'Wujek' mine

摘要

Since 1994 when it was started to carry our opening up and development works at a new mining area "Stara Ligota" at hard coal mine "Wujek" a change in kind of air-ducts took place used for ventilation of workings drilled with application of roadheaders. Products by "TESECO" company have been purchased. First positive results of application of air-ducts made by "TESECO" were accomplished during drivage of cross-cut P-4 o total length of 1450 m.
