The vast territory of the Republic of Sakha (Yakutia), located in permafrost conditions and scattered by impassable roads, creates a serious problem in the energy supply of the population. In this regard, throughout the territory of the republic there are small open-pit mines with a production capacity of 40 to 200 thousand tons of coal per year to meet the needs of local consumers. The advantages of small open-pit mines are the low cost of coal mining, reduction of transport and transshipment costs, provision of ...

Dumping during open-pit mining is one of the important processes on which the area of disturbed lands and the environmental friendliness of the technology as a whole depend. In permafrost conditions, the issue of dumping requires a comprehensive study of the technology, dumping processes and taking into account the strength, thermophysical properties of frozen rocks. In most cases, when developing small coal deposits in the North-East of Russia, favorable mining and geological conditions of bedding are used for in...

Peat belongs to renewable energy sources; therefore, research into the state of reserves, use and development of peat extraction and processing technology is of great relevance, especially in areas with harsh climatic conditions. On the other hand, other sources of energy, such as coal and hydrocarbons, are exhausted and depletable. Against this background, the development of innovative technologies for peat extraction in harsh natural and climatic conditions is of great interest and prospects. One of such regions...
