To reduce energy resource consumption in construction industry, housing and utilities infrastructure, it is necessary to maximize the new structural solutions use for the buildings and structures. The bearing and enclosing structures functions separation allows using the optimal design scheme with minimal steel spread for the supporting structures and effective modern thermal insulation materials for the enclosure. The advantages of grid shell structural system are durability, seismic stability, easy installation, dismantling, transportation, re-installation without the heavy equipment use; it also can be used in remote and hard-to-reach places. The authors propose the modules that can be used as exhibition pavilions, shops, cafes with the room height up to 6 m. Mass production of grid shell domes became possible with the advent of computer-aided design, allowing to perform the calculation and the structure three-dimensional model.

The most effective technical solutions have been those that provide for the supply of substances used for extinguishing to the combustion zone of the rock dump. When quenching rock on the rock dump is proposed injection (blowing) in a dry extinguishing agent, represented by crushed vermiculite (hereinafter referred to as the extinguishing agent), in pure form or in a mixture with alkaline substances. The problem of developing methods of extinguishing rock dumps, characterized by low cost and high efficiency, in the absence of additional environmental pollution is very relevant. The technology of suppression of waste rock dumps include the injection of suspended particles of vermiculite in contrast to the clay slurry or solution (suspension) of antipyrene. This allows to penetrate into the surface layer of the middle and upper part of the blade and insulate its lower part with non-combustible material.
