摘 要
我国富煤贫油少气的能源结构,决定了煤炭在国民经济发展中始终占据主导地位,并在未来较长时期内难以改变。面对每年因煤层气事故引发上千死亡人数和相当于我国天然气储量的煤层气资源储量的巨大反差,国家明令企业必须将煤层气抽采到规定标准以下方可采煤,并限制抽采浓度在30%以上的煤层气空排到大气中,同时给予抽采利用煤层气的企业一定财税优惠政策。目前,面对众多煤矿区煤层气开发利用技术,企业对如何筛选最适宜技术处于盲目阶段,对各种技术的适用性、经济性、社会性等缺乏系统认知;同时国家对推动煤矿区煤层气产业化发展、如何布局各类技术、如何制定适宜的煤矿区煤层气开发利用激励政策还处于摸索阶段,巫需一套适应中国煤矿区特点的煤矿区煤层气开发利用技术评价方法和评价工具。
为打破限制煤矿区煤层气产业发展的下游瓶颈,本论文着重围绕煤矿区煤层气利用对策及利用技术进行研究。在调研分析国内外煤矿区煤层气开发利用策略、利用技术应用、综合评价方法基础上,通过对煤矿区煤层气利用系统分析,依据煤矿区煤层气产业特色以及不同利用技术特点,从技术一经济一环境一社会四个纬度构建煤矿区煤层气利用技术评价体系和评价模型。依托评价方法,重点对最具有产业化前景的煤矿区煤层气发电技术进行综合评价,并进行不同政策、引入CDM

ABSTRACT
The energy structure of rich coal,less oil and gas determines The dominant of coal in the development of national economy in China, which will not change for a long time, With the comparision about thousands of death due to coal mining methane(CMM) accidents and the huge reserves of CMM extraction below standard, and limit emission of CMM concentration above 30%, and the extraction of enterprises would be get tax preferential policies. At present, with numerous CMM utilization technologies, the most suitable technologies for enterprises isn’t decided easily, without system cognition on applicability, economy, sociality about various techniques. What’s more, govermment is eager to know how tao promote industrialization of CMM, how to layout of technology, how to formulate appropriate incentive policy, which is promptly needed about CMM evaluation methods and evaluation technology tools considering China’s coal mine area charactera.
This paper was emphatically studied around CMM utilization countermeasures and technologies. In research and analysis of CMM by using technology strategy, CMM technical application status and comprehensive evaluation method, CMM technical evaluation system and model was structured through four aspects on technology, economy, environment and sociality. Relying on the evaluation methods, the CMM power generation technology as keynote was evaluated as well as sce
