THE NEED TO UP-GRADE COAL FROM THE LENA BASIN IN THE REPUBLIC OF SAKHA (YAKUTIA)

The key factor preventing more intense development in coal production in Yakutia is the low level of coal dressing and improvement as well as almost complete deficiency of coal processing facilities at coal mines. The problem of advanced processing of vital lignite from the Lena Basin is discussed from the viewpoint of stimulation of private business using the mechanism of public-and-private partnership in the field of municipal housing economy. The reduction of transportation cost in the structure of thermal energy tariff of heat supply owing to the use of local high-quality raw materials in the center, west and north of the Republic of Sakha includes cutting of cost connected with the creation of the described coal dressing facilities and enhanced reliability of heat supply agencies. The implemented experimental research shows that the increase in calorific power owing to energy-saving measures through the creation of strong and water-resistant heating briquettes is 43.2%.
