GOST R 58880-2020, Ship potable water system. Design rules, establishes the composition, selection and location of the main equipment and pipelines of the drinking water system on sea and river vessels and structures. The drinking water system consists of cisterns and pneumatic tanks, pumps, equipment for sanitary and hygienic water treatment, pipelines, fittings and means of change and control. The ship must have disinfection means for water stored on the ship more than 7 days. The tightness of the equipment and system elements must not be disturbed under the influence of hot water at the temperature up to 90 ° C.
GOST R 58869-2020, Mining. Method of directional hydraulic fracturing of roof softening in coal mines, establishes the basic requirements for the choice of technological schemes and parameters for laying wells during the work on the hardening of the roof of rocks in coal mines by directional fracturing. This method consists of several stages. First, a well is drilled by a drilling rig in the roof of the rock. Inside it, a special device creates an initiating slot - a cavity, whose diameter exceeds the diameter of the well. Then water is pumped into the well under high pressure and the rock mass is hydro-fracturing. When water is injected into the well it is prohibited to locate people near the wellhead (not closer than 10 m). Creation of oriented directional cracks in the solid rock mass allows effectively manage rock pressure.
GOST R 58948-2020, Automobile roads of general use. Winter automobile roads and ice crossing. Technical rules for construction and maintenance, applies to research and design of winter roads and ice crossings for seasonal motor transport movement. Automobile winter trucks are divided into federal, regional or municipal, local and private ones depending on their value. In terms of frequency, they are classified into regular, temporary and single use. In terms of location, they are divided into land and ice. In terms of service life - for regular and extended periods of time. Ice crossings are divided by length into small ones - up to 100 m, medium ones - from 100 to 500 m and large ones - over 500 m. According to the standard, the width of the ice crossing lane should be 5 m wider than the width of the most bulky cargo.
