Abstract

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 m3 per year.
In case there is a clear hydraulic connection between separate karst voids the common income of mining water from mining galleries of № 2 Novogrodivs’ka toward mine № 1 Novogrodivs’ka will be not more than 110-175 m3 per year (taking into account the value of income through the weathering zone and aquifer karst clamp).
In order to maintain the safe working condition for employees and hydro safety at mine № 1-3 Novogrodivs’ka, it is required to implement the engineering and technical measures to pump the extra mining water (175m3) per year), which corresponds to water income from № 2 Novogrodivs’ka toward № 1 Novogrodivs’ka. It is ensured in case there is a perfect hydraulic connection between the karsts.
