The research shows that the transition of coal production in Jiangsu Province has mainly experienced three phases, which are the quick transition phase from extensive growth to intensive growth （from 1990 to 1994）, the fluctuation phase （from 1995 to 1999）, and the transition back phase from intensive growth to extensive growth （from 2000 to 2003）. On the whole, the coal production in Jiangsu Province nowadays is still featured by extensive growth pattern and largely dependent upon capital inputs. Finally, from the aspect of the technology progress, improving the qualities of labor, changing product structures and improving enterprise management, this study puts forward suggestions on how to transfer the growth pattern of Jiangsu＇s coal-production into intensive type.展开更多

A new underground gasifier, long tunnel. large section underground gasifier, is designed. It is an important way to make LCG cornmercialization because the new gasifier can steadily produce gas with higher heat value by changing the flow state of air and gas in the tunnel.展开更多

To further the sustainable development evaluation system of coal mining cities in Heilongjiang province, based on the analytic hierarchy process （AHP） method combined with operational and scientific principles using Saaty＇s 1-9 scale method to construct the judgment matrix from five aspects, such as economic development and environmental quality, this paper establishes the comprehensive evaluation index sys- tem of sustainable development of coal mining cities in Heilongjiang province, including comprehensive index of industrial economic benefits and the contribution rate of science and technology. In addition, using fuzzy comprehensive evaluation method, a comprehensive evaluation is made on the indices of the four major coal mining cities of Heilongjiang. The result shows that the coal mining cities are not bet- ter than Datong of Shanxi province in many indices. The economic development and environment quality are the most important indices of the targeted layer influencing the sustainable development of coal min- ing cities of HeilonKiiang, and their index weights are 0.4358 and 0.2844, respectively. These two indices including comprehensive index of industrial economic benefit and the ratio of environmental protection investment to GDP are the key elements influencing the two aspects.展开更多
