Underground hard-coal mine as a hosting facility for a data processing center infrastructure

The paper discusses the possibility of using the coal mines infrastructure for hosting the data processing centers (DPCs). Modern technologies allow to consider the power supply system of a coal mine being sufficient to fulfill the high requirements of power supply reliability for DPCs. For this aim, the authors proposed the ”coal - energy resources - information” concept with respective structure of energy supply. As a means of increasing energy efficiency, it is proposed to use cogeneration and trigeneration on coal mine methane which allows to provide power supply to power consumers, heat supply to a coal mine and cold supply to a data center. The technical risks associated with the use of DPCs and trigeneration in coal mines were identified, providing basis for future research. In the conclusion, it was noted that the development of DPCs integrally with coal mines can increase economic efficiency, as well as create new workplaces and become a driver for the development of the IT industry in mining towns.
