The article identifies factors affecting the efficiency of insulating structures in mines. To prevent shrinkage of the pulp, it is proposed to add quicklime to its traditional composition, consisting of clay, sand and water. It was found that the presence of about 5-7% quicklime in the pulp prevents its shrinkage, and the presence of 20-25% quicklime in the pulp allows the pulp to swell by about 20% by volume. Experimental studies have been carried out to identify the aerodynamic resistance of porous layers of materials. The air permeability of the pulp and the effect of quicklime on the expansion of the pulp mixture, the air permeability of various compositions of the silting pulp, including the compositions used for the construction of filter bridges, have been determined. It has been established that the least air permeability is possessed by the pulp, which has quicklime in its composition.
