摘要：

Formation of leaks and "fistulas" in concrete lining of underground structures is associated with the local density of concrete, which is characterized by its water resistance. Capes and intermittent streams of groundwater negatively changes the resistance of individual sections of the concrete lining of mine workings. The solution to the problem of ensuring the filtration reliability of underground structures requires a quantitative assessment of the probability of leakages, and, therefore, the determination of the allowable filtration coefficient of the weakest local areas of concrete and reinforced concrete lining of underground structures. The problem of sealing the underground structure should be solved not only by improving the concrete lining. This raises the question of the measures to control the characteristics of the condition of the soil massif.
