ABSTRACT
The article is devoted to the creation of impervious curtains around excavations shallow burial. The patterns of the depth of penetration of high-pressure jets of fixing solutions on the technological parameters is based on the analyze. How to create elements of impervious curtains, allowing determining the volume of fixative solution for dispersed species, which depend on the filtration and mechanical properties of the veil. On the basis of experimental studies of the influence of established quality and quantity of fixing solution and the injection pressure on the filtration coefficient and the strength of the rock-cement elements is determined. The regularities of changes in the filtration coefficient to changes in the density of reinforcement solutions, which allows predicted the physical and mechanical properties of the new screens are settled.
