National economic and social development was greatly influenced by coal resources. The main purpose of this paper is to research how to keep balance in supply-demand of coal and optimize resources in Jinan City. Based on coal resources data from 1994 to 2010 of Jinan City, ARIMA model was established, status of supply-demand of coal resources was analyzed, predicting results were given byEcological resilience assessment of an arid coal mining,2020-2-1 · The mining intensity is the mining reserve per unit area of coal resources. Mining intensity affects groundwater (Fan et al., 2016); there is also a clear relationship with the degree of geological disaster development,which influences the ER of the study area. In this study, the mining strength is defined as the ratio of the coal reserves toCoal Mining in Indonesia to 2020 MarketResearch,2019-1-15 · Coal Mining in Indonesia to 2020 Synopsis Timetric's 'Coal Mining in Indonesia to 2020' report comprehensively covers Indonesian reserves of coal, reserves by state, resources and reserves by coal quality, proximate analysis of coal, the historic and forecast data on Indonesian coal production and by type, coal prices, historic and forecast coal consumption and consumption vs electricity
Limiting factors do not consider coal quality classification of coal resources based on global estimation variance (GEV) approach related to drill Corresponding author: Waterman Sulistyana Bargawa, Ph.D., Mr., research field: geostatistics and mining hole spacing analysis.Resource curse, environmental regulation and,2019-7-10 · The coal-mining cities have high energy consumption, high emissions, and low output, which lead us to ask whether they have a “resource curse” phenomenon, that is, resource dependence is negatively correlated with economic growth (Sarmidi et al., 2014; Smith, 2015). Some researchers have verified a resource curse in coal-mining cities andProximate and Ultimate Analysis Mining SGS,Ultimate Analysis Tests. Ultimate analysis tests produce more comprehensive results than the proximate analyses. SGS uses the results from ultimate analysis tests to determine the elemental composition of the coal including moisture, ash, carbon, hydrogen, nitrogen, sulfur, and oxygen (by difference).
