基于SD的煤炭矿区节能减排仿真与调控

煤炭矿区在生产煤炭能源的同时,会产生大量的能耗和排放,而降低煤炭产量必然会影响矿区的经济效益.如何协调经济发展与能源消耗、污染排放之间的矛盾,是煤炭矿区亟待解决的难点问题.通过分析煤炭生产各环节节能与减排要素、煤炭矿区节能减排系统的复杂结构和系统内部的动态反馈机制,建立了煤炭矿区节能减排系统动力学模型,并对煤炭矿区不同的发展方案进行了仿真模拟.结果表明,矿区总投资、煤炭生产投资、环保投资、各种吨煤能耗量等因素在煤炭矿区节能减排系统中发挥了重要的影响作用;可以通过增加矿区总投资,优化煤炭生产投资与环保投资比例,降低吨煤能耗量来达到矿区经济与节能减排协调发展的状态.

Simulation and Adjustment of Energy Saving and Emission Reduction in Coal Mining Area Based on System Dynamics

Coal production is accompanied by large amounts of energy consumption and emission,while reducing coal output would inevitably influence economic benefits of mining area.How to coordinate the conflicts between economic development,energy consumption and pollution discharge is an urgent and difficult question for coal mining areas.This paper establishes a system dynamics model of energy saving and emission reduction in coal mining area,as well as conducts simulation of different development plans,based on the analysis of energy saving and emission reduction factor of coal production links,of the complex structure of energy saving and emission reduction system in coal mining area,and of the dynamic feed-back mechanism inside the system. Result shows that total investment,coal production investment,environmental protection investment and coal energy consumptions per ton play important parts in energy saving and emission reduction system in coal mining area.By adding total investment and refining the proportion between coal production investment and environmental protection investment,as well as reducing coal energy consumptions per ton,harmonious development of economic and energy saving and emission reduction could be achieved.
