GEOLOGICAL STRUCTURE AND COAL CONTENTS OF THE GUVILGRINSKY HOLLOW OF THE GONAMSKY CARBONIFEROUS AREA OF THE SOUTHERN YAKUT COAL BASIN
Southern Yakut coal field (fig. 1) is large and reliable base of the high-quality coked and steam coals in the east of the country. In the 70th years in the south of Yakutia forming of the Southern Yakut TPK was begun, as predetermined considerable strengthening in this region of exploration works on coal. Now in the pool it is developed by an open method Neryungrinsky, Elginsky fields and certain sites on Denisovsky and Chulmakansky fields. Absence near the operating Neryungrinsky coal mine of the coalfields suitable for open-cast mining, and also finite useful lives of the Neryungrinsky field (till 2018–2020) caused expansion of search works on coal on flanks of the pool, perspective on identification of the powerful coal layers suitable for development by an open method.
