WATER BARRIER FOR LOCALIZATION OF BLASTS OF COAL DUST IN MINE WORKINGS

摘要

A water barrier for localization of blasts of coal dust in mine workings comprises several cross rows of polymer vessels filled with water and placed in the upper section of the working on long rails. All the vessels along the whole barrier in the mine working are hydraulically connected to each other through connection to each other with corrugated rubber-fabric hoses. All the vessels are in one horizontal plane, and one of the vessels hydraulically connected to each other is equipped with floater valve and is connected to the mine main through a valve.
