Coal ash and slag waste are the products of coal processing that can be recycled into other useful products, but most part of them is accumulated in dumps which causes several environmental consequences. The paper presents a review of the most promising ways of coal ash and slag waste processing based on patent analytics and scientific literature review. Since the patenting process usually comes before innovation implementation, this approach allows to identify the most promising technologies even if they haven’t been implemented yet.
The article analyzes the role of intellectual resources in the development of extractive industries through research on promising technological solutions for the main stages of technological processes. The relevance of the study lies in the possibility and necessity of using patent analytics as a tool for forming growth points for high-tech sectors of the economy in resource-type regions. The authors suggest that the oriented adaptation of patent analytics tools will solve a large-scale scientific problem - to identify patterns and dependencies of changes in the mining and geological conditions of subsoil use and, accordingly, the main parameters of mining machines, over time and develop a methodology for predicting and justifying the promising parameters of various mining machines as one functional purpose, and multifunctional, ensuring their efficient operation for a given period of time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
