As a result of the research, system approach to the management of mining, utilization, export and import of national coal resources has been formed. The comparison of export and import prices for metallurgical coal and anthracite led us to the conclusion that export-import operations are ineffective, since export prices for anthracite are lower than import ones. It has been proved that it is unprofitable for the national economy to export coal at low prices in situations of coal mining reduction in Ukraine. Analysis of black coal, anthracite (2701), coke and semi-coke, retort carbon (2704) export and import`s geographic structure has been made. It has been found out that the Russian Federation and the USA are the main importers of black coal and anthracite, export flows were concentrated in Bulgaria, Turkey, Belgium and the Russian Federation. It has been specified that coke, semi-coke and retort carbon (2704) during 2011-2018s were imported mainly from the Russian Federation, the USA and Poland. Export destination was the Russian Federation. It has been proposed to use system approach to rational mining, use of the country's available mineral resources, taking into account exportimport flows, external and internal markets pricing, as well as the resource component of national security.

The mining industry plays a significant role in economic growth and development. Coal is a viable renewable energy source with 185.175 billion deposits in Thar, which has not been deeply explored. Although coal is an energy source and contributes to economic development, it puts pressure on environmental sustainability. The current study investigates Sindh Engro coal mining’s impact on environmental sustainability and human needs and interest. The Folchi and Phillips Environmental Sustainability Mathematics models are employed to measure environmental sustainability. The research findings demonstrated that Sindh Engro coal mining is potentially unsustainable for the environment. The toxic gases (methane, carbon dioxide, sulfur, etc.) are released during operational activities. The four significant environment spheres (atmosphere, hydrosphere, biosphere, and lithosphere) are negatively influenced by Thar coal mining. The second part of the analysis results shows that human needs and interests have a positive and significant relationship except for human health and safety with Sindh Engro coal mining. Environmental pollution can be controlled by utilizing environmentally friendly coal mining operations and technologies. Plantation and ecological normalization can protect the species, flora, and fauna of the Thar Desert. The government of Pakistan and the provincial government of Sind should strictly check the adaptation of environmental standards. Furthermore, the researchers should explore the environmental issues and solutions so that coal mining becomes a cost-efficient and environmental-friendly energy source in Pakistan.
