Abstract

Considering characteristics of geological and mining conditions at the Kansk-Achinsk brown coal basin, the authors prove the necessity for non-standard geotechnology application. A new predrainage-free geotechnology application has been described for watered flat coal strata, which ensures complete utilization of mineral reserves and mined-out areas as well as improves environmental safety. It is recommended to selectively extract hard dirt inclusions, if present, by hydraulic mining scheme. The article discusses feasible after-mining utilization of the disturbed lands.
