Patterns of gob-water inrush in Chinese coalmines [PDF]
Water Practice and Technology, 2017 Gob-water is a serious hazard in Chinese coalmines. Such inrushes have caused more than 80% of the coalmine water accidents recorded in recent years. This study is based on reviews of past gob-water hazard cases in China. Six inrush patterns are suggested, caused by gobs exposed by tunneling, channeled by faults, or fissure or caving zone channeling ...
