Water trough stop for underground installation - comprises several water-filled troughs bursting under effect of sudden excess pressure

摘要

The water troughs (22) are arranged in a transport frame (2), and at least one of them can be moved out of the frame at least one one side. At least one fixed and one movable trough are arranged one behind the other in the frame, and they occupy more than half the width of the frame. The movable troughs are suspended individually or in groups on a rail system (26). Each rail system consists of a stationary rail fixed in the frame, and at least one movable rail. Where the water troughs are grouped, each group comprises at least two troughs, arranged one below the other. USE - In mining, as a water trough stop, in which water-filled troughs suddenly burst under the effect of sudden excess pressure.
