Product Informations

JULI® explosion-proof water barrier bag is used to isolate the spread of gas (combustible gas) and coal dust explosions. To prevent coal dust explosions and control the expansion of coal dust explosion disasters, ensure that coal and semi-coal rocks are in each mining area, at the upper and lower exits of the tunneling surface, and also transport roads, etc. to ensure sufficient water volume, To prevent the spread of gas and coal dust explosion accidents, the propagation of coal dust explosion shock waves is blocked.
