The paper considers the problems associated with the imperfection of legal support of the processes of development and utilization of mineral wealth and, first of all, with the absence of the concept of “dilution of reserves” in the regulatory legal acts. It is necessary to redefine fully formed procedures for licensing the right to use mineral deposits, as well as a recognized system of taxation. Organizational and technical solutions to improve the legal norms related to subsoil use by existing coal mining enterprises are outlined below.
