Study of a Low-Cost Method for Estimating Energy Fuel Resources in Anthropogenic Sediments

Abstract

In 2021, at the request of PJSC “Dnepropetrovsk Coke Plant”, city Kamianske, we conducted research at the facility where coke-chemical waste is stored on one of the coal waste collectors. The study area was 9.37 ha. The research subject was anthropogenic formations, which were formed due to the storage of coal-floated sediments on the company’s premises. The research aimed to determine the characteristics and analysis of the quantity and quality of coal accumulations, determine the retention of the insulating layer and its composition, and create maps of the quality and capacity of accumulated anthropogenic sediments. The ordering company decided to use both – the latest ground penetration technology and the traditional methods of drilling and laboratory, thanks to which an unusually large number of parameters were obtained and processed during the research process. Similar research was conducted on other industrial facilities, but to a much lesser extent; since we have implemented a combined, comprehensive methodology for the assessment of anthropogenic deposits, because of which the effectiveness of geological research and economic assessment increased, the time of conducting research shortened to 40-45 calendar days, and the cost of such tests decreased five times. At this stage, some things could be improved in the methodology, such as imperfection of the mathematical model and methodology of statistical data processing. These errors will be eliminated during further modelling work under the prepared implementation plan for the tested methodology.

Hydrogen Storage and Combustion for Blackout Protection of Mine Water Pumping Stations

“…In emergency situations at another pumping station, hydrogen can be transported there to generate electricity and heat [26,35,57]. When the national grid runs out of power and information is obtained that the failure will drag on, the pumping station will go into an emergency operation mode.…”

“…In accordance with the guidelines of the European Commission within the framework of the European Green Deal and in Regulation (EU) 2021/1119, the European Climate Law, the modernization of pumping stations is being considered. For at least the partial coverage of the energy demand, the use of renewable energy sources (RESs) is envisaged, including photovoltaic farms with energy storage adapted to the needs of pumping stations [34][35][36]. The considerations presented in this article also apply to the broader aspect of using the existing mine shafts.…”

“…Storage of electricity in batteries is only possible in the short term (preferably within the same billing day). For this reason, the decision model of Option 2 provides for the storage of excess electricity generated only for own operation of pumping station equipment during the non-sunny period of the solar day (Khomenko, Jelonek, 2023;Magdziarczyk et al, 2023).…”

The Cost Reduction Analysis of Green Hydrogen Production from Coal Mine Underground Water for Circular Economy

“…The project is part of the Just Transition process and is an opportunity for regional development thanks to the introduction of modern technological solutions [23,24]. The variant project in question will create new markets related to modern transport and an energy mix based partly on renewable energy [19,25]. The presented variants of energy self-sufficiency also provide the opportunity to revitalize post-mining assets, which would otherwise be difficult to adapt to another purpose [26][27][28].…”
