USE OF BURNED ROCKS IN UNDERGROUND LAYING OF CABLE LINES IN THE CRYOLITZONE
The relevanceof the research is caused by the need to develop natural resources and expand the residential areas of the arctic regions of the Russian Federation. The development of these territories in the permafrost zone is complicated by the negative influence of cryogenic processes on the constru...
