ECONOMIC TRENDS IN THE LIQUID MINING WASTE SURVEY AND MONITORING IN THE ARCTIC ZONE FOR THE PURPOSE OF DECLARING THEIR INDUSTRIAL SAFETY
The article presents correlation and dynamics analysis on various activities that are a part of the geological, geodetic and hydrographic survey and monitoring of a liquid mining waste storage located in the Arctic zone over a five-year period of declaring the protective hydrotechnical facilities safety. The work costs for the five-year declaration cycle were calculated on an example of a hydrotechnical tailing dump of a major mining enterprise located in the Murmansk region, a part of the Russian Arctic zone. The data from 2013 to 2017 declaration cycle were analyzed in detail. The main trend identified is uneven distribution in the work cost growth by years: a period of relatively smooth cost growth is seen during the first three years, primarily due to inflationary processes; an abrupt growth of work cost is observed in the last two years. Such increase is associated with the expansion of a work program due to increase in field (and, proportionally, laboratory) geological and geodetic activities. On the basis of the research, recommendations are given for smoothing the fluctuations in the cost loading resulting from the uneven distribution of the work cost by years within the declaration cycle.
