Abstract
Optimizing the industrial structure is an important way to address resource constraints, achieve sustainable development. In this study, a planning method that combines the superstructure modeling concept and the mathematical method of mixed integer programming is proposed to investigate the optimized results of the coal industry under given constrained water resources, with 4 major coal application industries and 14 coal technology categories are considered. The results indicate that an increase in available water resources is associated with an increased local utilization rate of coal. Under the Water Rights Replacement Scenario, the local utilization rate of coal reaches 24.9%. Changes in available water resources significantly impact the coal chemical industry. In addition, significant reduction by 25% in carbon dioxide emissions requires 70 percent reduction in IDCL and CTO production. The policy implications for the development of the coal industry are also provided in the end.
