Abstract
Methods of quarry water disposal at domestic and foreign open-pit mines are considered, and it is found that mining of watered lignite deposits in the Kansk-Achinsk basin using traditional drainage methods is not quite efficient. A technology is proposed for mining a watered lignite deposit without draining it, which makes it possible to reduce unproductive costs for coal production and mitigate the negative effect of open-pit mining on the environment.
