Summary:A mine tunnel ventilation control device and method for constructing same quickly with an easily transportable matrix material to provide a rigid flame retardant barrier wall. The air flow stopping includes a peripheral frame extending about and across a tunnel opening to which is secured a matrix material, preferably in the form of a composite including a sheet of very strong grid material, such as a biaxially oriented integral geogrid or the like, bonded to a sheet of a textile material, such as a non-woven, needle punched, geofabric or the like which spans the apertures of the geogrid. At least one side of the matrix material, and preferably both sides, are covered with a sealant composition to prevent passage of air through the mine stopping and to develop structural rigidity.
