The "Voda Donbassa" utility company's Siverskyi Donets-Donbas Canal is considered critical infrastructure and at increased risk, as existing environmental threats have been identified (significant technical malfunctions in connection with military operationsbreach of the waterproof canal-bed; damage to the pipeline's water-tightness; flooding along the path due to significant water loss and, as a consequence, development of dangerous geological processesswamps, landslides, surface subsidence, rising groundwater levels; a possible complication of the humanitarian and sanitaryepidemiological condition in the region is the presence of the prerequisites for man-made accidents to occur at environmentally-hazardous chemical, metallurgical, and energy enterprises that use large volumes of water in their technological process) and recommendations given for minimizing the risks of the beginnings of man-made environmental disasters (development of plans for the localization and elimination of the consequences of accidents, where they are lacking; measures to prevent breaching the integrity and waterproofing of the Siverskyi Donets-Donbas Canaltechnical inspection, planned and preventative maintenance work, repair work; monitoring the canal's hydrological and hydrogeological systems, hydraulic structure technical condition, ensuring systematic monitoring and renovation of the water supply system; implementation of measures for drainage of land in areas of flooding in order to reduce the negative impact). In connection with the passage of the Siverskyi Donets-Donbas Canal route through the line of armed conflict, it is necessary to create "secure zones" with a radius of 5 km where the canal intersects the contact line in order to prevent their destruction due to possible shelling.
Annotation. The current hydrogeological state of Selidove mine group (named after D.S. Korotchenka, Selidivs'ka, № 2 Novogrodivs'ka and № 1-3 Novogrodivs'ka) is characterized by damaged geological environment, which was derived from coal extraction. According to the geological zoning the Selidove mine group can be classified as Donetsk hard-coal basin within Chervonoarmiqs'ka monocline damaged with tectonic framework. In this study the estimation of hydrogeological situation around the mine № 1-3 Novogrodivs'ka was performed. In undertaken the evaluation the flooding of mining galleries of № 2 Novogrodivs'ka, Selidivs'ka and, mine named after D.S. Korotchenka was taken into account. In terms of surveyor observation data the filtration of mining water from mine № 2 Novogrodivs'ka toward mine № 1 Novogrodivs'ka is possible through the nordic and south blocks, which divide the mining activities processes. The speed of flooding level change at mine № 2 Novogrodivs'ka is about 0.12 meters per day. Bearing this in mind the required time to reach the ground surface (absolute height) +185 meters is about 532 days starting from September 2019. Keeping in mind the volume of extracted underground space and the flooding factor 0.4, the common forecasted water income is about 65-130 m 3 per year.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
