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.
